Ford F-150 - 1997-2003 :: A/C Won't Take Charge?
I have an 03 F150 that I put a 4bt 3.9 cummins diesel in a couple years back. I'm just now working on ac issues. I have custom lines built and have a new drier in it. I am uncertain of the location of the expansion valve. I have not found a diagram of where that would be. It is a supercrew so it has the large condenser and I don't remember seeing the expansion valve/filter in that line when it was apart.
So I pulled full vacuum on the system and let it set for over an hour and it held the full vacuum. I plugged the Freon to it and it pulled just a small amount into the system. with the vehicle off it registered about 90lbs on both high and low with just the one can attached. I closed high side and jumped the ac pressure switch and it dropped to about 30 lbs on low side, but would move back up to 90lbs when I turned compressor off. It would not pull anymore out of the can. Do I have a plugged filter somewhere?
Ford F-150 - 1997-2003 :: 1999 - Charge Light Won't Go Off?
I have a 99 Ford F-150 Lariat 5.4L 4x4. I was driving my son to work and the truck died. My son-in-law gave me a jump and as soon as he removed the jumper cables my truck died. We took the alternator to Auto Zone and had it tested, twice they tested it and it passed. We took the battery to them for a battery test and it was dead. Got a new battery and put it in the truck and the truck starts. The voltage on the battery was 12.4 off and when we turned the truck on the voltage went to 12 so we replaced the voltage regulator on the alternator and now I get 13 volts on battery while it is off and on the voltage goes a little above 15 and the charge light will not go off. What to look for to try and fix this problem. What can cause the light to stay on? I can push down on the belt a little but my son-in-law says the belt is ok, it does have a few cracks in it.

Had a little fender bender. Right after that i noticed the battery red light was on. When I got it home I took the solenoid off the firewall (all the battery wires meet here). When you put 12 volts to the small terminal, the solenoid pulls in and the two big terminals are connected together. That works. When installed on the truck and startup, I have no 12v voltage at the small terminal. Don't have a diagram, but service manual says something about fuse #14 under the dash feeding the "battery cutout".. Checked that fuse and its o.k. .... where does the 12 v signal to the solenoid come from ? I assume somehow it triggers after the alternator starts charging ?

I have a quick question, I just replaced the head gaskets on my 4.6 with 301,000 miles on it and now my battery only charges when you punch it and when you lift off the gas pedal, in town it does fine, but on drives 25 miles on the highway the battery guage goes to the line on the bottom. What could be causing that?

I have a vehicle I am storing for the winter, but do want to start it up on occasion just to keep it fresh. my question is this. I put a trickle charger on the battery to keep it charged up, its one of those chargers you can leave on indefinitely, once the green light goes on the charger, it goes into maintanance mode. but I've had the charger on for a week now and it seems the battery won't take a full charge. to put the battery charger into maintance mode. is it dangerous to keep charging a battery that won't fully charge up?

01 F-150 7700 ed.
I have a 4R100 Tranny with 139K miles. It has been rebuilt. Ever since the rebuild (over 10 yrs ago), if I park the truck for a week or so or more, I will end up with a decent size puddle of trans fluid underneath the truck. I took it back to the shop that did the rebuild a couple times, but they could never find anything. It leaks enough to where my fluid level drops enough to cause the transmission to slip in a U-turn because the pickup tube becomes uncovered. I have a couple theories, but am wanting to hear from the collective.
Theory #1 When I park it on my slightly sloped driveway I don't regularly use the parking brake, so it rests on the gears, which eventually forces fluid out an overflow or breather tube.
Theory #2 (a very thin one) due to pressure changes associated with the weather, fluid is somehow siphoned out a breather tube due to some blockage internally in the tranny to where it's not equalizing with the outside air and has a high pressure within... ( i kinda laugh at myself for this one, but I am at a loss over the source of this)
Ford F-150 - 1997-2003 :: 1998 F250 XLT - Noisy And Occasionally Will Pop Out Of 4wd
I have a 98 F250 Supercab XLT. 4wd with 3:73 gear ratio. twist 4wd on the dash. Truck runs great but when i switch to 4wd it makes noise and occasionally will pop out of 4wd. The noise starts at almost no speed. I can hear it at less than 5 mph. and only gets worse as i increase speed. (sounds like a bad wheel bearing) - But only in 4wd/ nice and quiet in 2wd.
I used sensors and ear phones to pinpoint the noise. It appeared to be coming from the front differential. I opened the pumpkin found clean fluid and no metal bits or any visible unusual wear. I changed the front diff. with another used unit. The noise is still there strong and unchanged. The wheel bearings and axles seem to be all right.
Ford F-150 - 1997-2003 :: Lights Will Occasionally Blink Off And On With Ignition Off
Ok, so I got a really wierd problem with headlights. 2001 F150, Supercrew, 4x4, 5.4L Auto lights and fog lights. Sitting with ignition off, light switch in "off" position, doors not locked - lights will occasionally blink off and on(more of a flicker). Symptoms go away if I lock with remote.
With engine running, lights "on" position. Turned lights to "park", they started to flicker, back to on, still flickering. Switched to off, still flickering. Switched to "auto", lights stayed on with no flickering.
When lights flicker, I can hear a rapid clicking under the dash somewhere(relay of some sort?). Headlight is a bit wobbly. But when I wiggle it, it has no effect on flickering. From what I remember, likely culprit is the GEM module.
Question: does a new module have to be programmed in any way or is it plug and go? I have a new headlight switch coming.
Ford F-150 - 1997-2003 :: P0401 Code / Occasionally Missing Under Load
Have a p0401 code which I need to diagnose and solve. However, I don't believe the symptoms are indicative of the EGR system. Its a 1999 4.6L auto approximately 200k miles. Truck runs fine until it warms up, and then occasionally it begins to act like its missing under load. steady state on the freeway it may have an occasional miss, but put a load on the motor and the miss becomes real bad. This doesn't seem to me to be symptomatic of a P0401 code, but I don't really understand the EGR system enough to be sure. Searching on the forums for other p0401 codes doesn't seem to have the same symptoms.

View 9 RepliesFord F-150 - 1997-2003 :: 1999 5.4L - Idle / Running Rough Occasionally
I purchased a 1999 F-150 Lariat 4x4 automatic transmission about a year ago. When I did, the previous owner told me about an idle issue that he has occasionally. He said that the issue was with the IAC. He claimed that he had replaced it several times but "it was hard to get a good aftermarket IAC that actually works". He said he tried several, but it never fixed the issue. That sounds like he wasn't replacing the defective part to me, but I don't know. This is my first truck to ever purchase.
Fast forward a bit (about a year), and I have had intermittent issues with idle and running rough since I bought the truck. I don't drive the truck that often, but they are becoming more common, so I want to get things fixed now.
Issues:
1. When running at idle, especially in park, the idle seems to fluctuate and never stay consistent. The idle drops as soon as I put it into drive, and the truck jerks a bit when going into drive because the idle was too high in park. It has never died while at idle, however.
2. When driving, especially up a slight or moderate hill, the power seems low and the truck starts to ping and jerk. The only way I can avoid the jerking is to stomp on the accelerator and go into a lower gear. And even when doing that, I still can notice an ever so slight jerk.
3. This past week, it was rough for an entire 40 mile journey on the interstate. Slight ping the entire ride home. When I pulled into the driveway, it was jerking until I turned it off. I haven't tried to drive it sense.
Potential issues:
1. IAC - maybe the previous owner was right. Maybe I should replace it again, or clean it with some carb cleaner.
2. Cam Phasers - I saw some posts about this on the forum.
3. EGR valve - Also saw some posts about this.
4. Maybe even the transmission? It doesn't seem to have an issue going into or out of gear, though.
Ford F-150 - 1997-2003 :: 1998 Truck Will Not Start Occasionally And Error Codes
I have been having odd problems with my truck for several weeks now and what the problem may be. Occasionally the truck will not start. This happens after it has been run for an errand or to church. The truck turns over but no ignition. Sometimes if I pump the gas pedal very quickly I can get it to start. Other times I have to sit and wait about 5 minutes. I have gotten the following two error codes - P1506=Cylinder Head Temp Sensor and P1299=Idle Air Control Overspeed Error. For two days the "check engine" light was on, but now it has gone out. I have searched for an answer to this problem on these boards and one possibility may be a vacuum leak. Is this the most likely? 1998 Triton 4.6 ....

Truck ran fine yesterday. Go out to get in it today and the dome and door lights do not come on. No chime when inserting key, turn key and nothing. No dash lights, no head lights, no clicks, no buzz. Absolutely nothing.
I checked and the battery has 12.8Vdc. Both master fuses on the firewall read good. All fuses in the under hood fuse box read good. I am confused. Where to start looking?

View 1 RepliesFord F-150 - 1997-2003 :: 4.2L V6 Hard To Start / Occasionally Running Rough And Losing Power
I recently bought a 4.2L V6 2003 F150 with only 20,350 original miles. This car belonged to an older gent who barely used it, then passed on about 3 years ago, and truck sat around barely used by anyone. When I picked it up I ran some Seafoam through the first two gas tanks as it was occasionally running rough and losing power. Since then truck has been running incredibly smooth, but in the last few days it is getting harder to start. If I pumped it two or three times it would start OK, but today I have had to pump it while cranking it to get it to start. ( the pumping may have nothing to do with it starting)
I am replacing the fuel filter in the next couple of days, as any accumulated junk that was in the tank or lines is now probably in the filter, but it seems that a badly clogged filter would also give me some problems running, and it runs really smooth once it starts. I get a pressure gauge, (I understand the rails have a pressure test port) what pressures should I expect at what moments?
Turn key on :
Crank engine :
I am brand new to the F150 and trucks in general.
Ford F-150 - 1997-2003 :: Truck Will Occasionally Flash Every Light On The Dash - Cranks But Will Not Start
I bought my 2003 F-150 XL (4.2L V6, 2WD, had 165k miles when purchased, 170k now, battery is a Napa brand manufactured in April 2012) in June 2012. A few weeks after I got it, I started having some weird issues. The check engine light came on and I went and had the codes read at Advance Auto. They were P0171 and P0174, lean bank one and lean bank two. The vacuum leak causing these codes isn't the issue I'm dealing with, it is the electrical problem.
The truck will occasionally flash every light on the dash (service engine soon, low fuel, oil, coolant temperature, seat belt, door ajar, and a couple others if I remember correctly) when I turn the key to power on the electronics. The first time I turn the key all the way to crank the truck up, it cranks fine, starts up, and dies within 3-4 seconds. The second time, it does the same thing. Third time, it just cranks and cranks, but will not start. After cranking and not starting a few times, the truck basically just clicks because the battery is run down.
This problem has happened randomly since June. It might be six weeks, one week, or only a few days between occurrences. The last two times it did it, I took the battery out of the truck, put it on a 6 amp charger overnight (about 8 hours), put it back in the truck, and it still wouldn't start, lights still flashing, etc. I gave it about 2-3 hours and both times the truck would start strongly and without incident, and the service engine soon light was off.
It rained here a LOT this summer, so I figured it might have something to do with driving through standing water at various speeds. The problem seems loosely associated with rainy weather (it rained last Saturday and I had to drive approximately 10-12 miles in it), but now it has started something new.
Yesterday afternoon, I tried to start the truck and it did the above described problem. I took the battery off and put it on a 10 amp charger for about six hours yesterday and left it disconnected overnight. Reconnected it this morning, gave it a couple of hours, still nothing. I remembered one time a while back that hitting the odometer reset button made the dash lights stop flashing. I held down the reset button and everything stayed lit up, but stopped flashing. Turned the key with the reset button held down and the truck started right up, but the dash kept flashing.
Turned it off, tried starting it without holding down the odometer reset, would crank, but not start. Tried starting it while holding down the odometer reset again, started right up. When I turned it off and tried it a third time, it just cranked for about six seconds before I gave up. This time, the oil, coolant temperature, battery, and service engine soon lights stayed lit (not flashing, they were solid) and the truck refused to start anymore.
Before it did the odometer reset BS I thought maybe I could figure it out because while it was a ghost of a problem that randomly came and went, it was always the same issue. Now I'm COMPLETELY lost.
Ford Wiring/Electrical :: 1999 F150 - Battery Draining From Full Charge To No Start In 1 To 2 Days
My neighbor's kids truck battery drains from full charge to "no start" in 1-2 days. 1999 Ford F-150 w/ 4.6L engine. He has already.....
1) Replaced the Battery.
2) Replaced the GEM module.
3) Replaced the Turn Signal Relay.
He did all this before I looked at it....
I checked the following....
1) Truck off, doors closed, hood open... Amp meter shows 3.6 amp draw. When 1st hooked up, shows 4.2 amps... after a while drops to 3.6.
2) To isolate the draw, we pulled fuses while checking current draw at battery.
a) Under Dash fuse Panel. (Yes, with door closed) We remove fuse #15 "stop lamp switch, speed control, brake shift interlock, ABS, PCM,GEM, RABS test connector". (Really... couldn't be more stuff?)
b)Under the hood is another fuse box (drivers side). We remove Fuse #103. "Junction Block Battery Feed".
3) Found that if we remove the #15 fuse under the dash with the door opens, all interior lights flash on/off at about 1 second intervals... weird.
4) Again, another weird one... with the fuse #15 removed and door closed, the "ABS" indicator and some other indicators and dash lights are staying partially lit... not fully lit.
5) The only "aftermarket" stuff i can see is a dealer installed trailer brake system. Wiring looks professional and disconnecting it does not remove the amperage drain.
I'm hoping that one of you wizards will give me the "slam dunk"... if this happens, it must be that. Can I be so lucky? And, yes. I have my own '06 F-150 that i absolutely love. 6-cyl., manual trans, stripped down without even power door locks... my kinda technology.
