Ford F-150 (2004-2008) :: A/C Stopped Working
2005 F150 5.4L A/C stopped working. All fuses are good. If I jump the two inboard terminals on the relay under the hood my A/C comes compressor engages and A/C works. The relay seems to be good, so where do I go next? The relay has no diagram on it so i do not know which side is coil and which side is "contact/switch" but if I plug it in I can feel it "click". How do I definitively test this relay and if it is working, what is the next step to troubleshooting.

My 04 f150 fx4 has some cruise control issues. The cruise doesn't work at all and the self test doesn't do anything on my truck either. I tested the disengage switch which tested good but replaced it anyway. I've checked all brake lights and replaced the 3rd light which was burned out. I've unplugged the brake switch and reconnected in case of loose connection with no luck. I removed the brake switch and tested as follows.
Top to bottom pins 1-6 for sake of this discussion. Pins 1 and 2 no continuity until brake button is pressed. Pins 3 and 4 are blank so no test performed. Pins 5 and 6 tested the same as 1 and 2 so am I correct in saying the switch is good? My truck will shift through all gears and back without ever applying the brakes. Bad shift interlock inside the shift console? I haven't torn into that yet but it's the only thing left I can think of. Is there any tests to be run on it with a multimeter?
Ford F-150 (2004-2008) :: 4x4 Not Working - Bad Front Differential?
Working on a 2004 Ford F150 4.6L. No 4x4. Replaced both IWE front actuators. (Neither one would hold vacuum). Still no 4x4. I realize I have vacuum issues and may be excessive wear on gear teeth of the front wheel bearings. The issue that really bothers me is the front differential. Having placed the truck on jack stands and running in 4x4 should both front wheels be turning ? The right front wheel turns and the left front does not move. Is this normal or should I pull the front differential cover off ?

I have the Ford PowerCode remote start on my '08 F-150. Seperate one-button unit. The truck sat for about 5 days, and today I hit the remote as usual.......nothing. No lights come on, no horn beep,....nothing. I use the keyless entry, which works fine, and use the key to start the truck. Starts fine, everything works fine, but no remote start. Seems weird as it worked fine the last time I used it. I bought the truck new in August, and it was dealer installed. Batteries in both remote start units are ok. What would make it not work now?

My reverse lights do not work and it is not due to the bulbs. Guy at autozone said it is the neutral safety switch. Does this sound correct? And I have done work on my truck myself, is this a difficult fix?

I have a 2006 F-150 Supercab King Ranch 4wd. The 4wd is not working. Took it to the dealer and they tell me the 4wd module is not communicating with the PCM. It is my understanding that this problem is rare...like 1 in a million. Ford wants to replace the entire PCM. In the past, I have had electrical problems with this vehicle due to corroded wires.
View 9 RepliesFord F-150 (2004-2008) :: 4wd Won't Working And Making Noise?
2004 F150 Super Crew Lariet 4x4 with limited slip. Center console with electonic switch 2wd/4hi/4lo on dash right of steering wheel. My 4 wheel drive does not work.
When the truck is in 2wd I have no issues, no sounds(I've heard anyway) or anything. The only questionable is when turning with wheel at full lock in either direction at low speed, my front wheels grab/lunge. Not sure if that is normal or not on these trucks.
When I put it in 4wd in the snow, it acts as though it wants to engage, but the second any power is applied to the wheels, the back wheels just spin and it makes a higher pitched grinding/chattering noise up front. It will also lightly clunk into 4wd with little power applied to the wheels, but once it has accelerating power applied the front diff "pops" and is clearly no longer engaged.
When in reverse in 4wd, it makes no noise, but still doesn't work.
Yesterday I had it in the shop for an oil change and to rotate my tires. While it was all off the ground I turned the ignition on and put it in 4wd. Both back wheels turned it the same direction(limited slip) as they should, and the front left wheel turned fully engaged with them. The front right wheel did nothing and turned freely on its own(assuming because front it open diff?). One oddity noted, when the back wheel were rotated one full revolution, the front rotated 2 full revolutions(also assuming this is because of the front diff being open and rear being locked?).
When I spun both front wheels by hand regardless of 4wd turned on or not, IIRC, they both made a clicking/ratcheting sound as the spun.
I left it in 4wd when I brought it back down on it's wheels and backed it out of the shop into the unplowed area of snow, I lunged the throttle a touch and the front end dropped as the front wheels gripped and slightly broke loose in the sticky snow. It was fully engaged and working properly for a second. I then put it in drive and tried to move forward, soon as any power was applied it "popped" out of engagement in the from diff and was back to 2wd and light grinding noise.
Another note, our first big snow fall a few days back is when I first had a real issue with the 4wd not working at all. It had snowed pretty well and I didn't feel like shoveling the driveway because I was running short on time to make it to work and my wife had the day off work and didn't need to go anywhere. I started it, put it in 4wd, let it warm up a bit, proceeded with trying to leave. This is when it all began with the 4wd not working at all and grinding. As it made that noise, it sounded pretty light to me in the cab even with the window down. But, as my wife noticed me stuck in the driveway she stood in the front door watching with the glass storm door still closed. She said she thought that "light" grinding noise I heard, was actually quite loud from where she was standing, 60+ ft away.
Previous issues I've noticed with my 4wd that may diagnose my exact issue, it has had a frequent issue the past year or so with, when engaaged, if I applied too much acceleration, from a stop or not, it would suddenly "pop" out of engagement as I've previously noted on, but I would immediately let off the throttle and it would reengage right away.
On two other occasions, it has refused to engage into 4wd no matter what. I simply contributed it to the extremely cold weather during the occurrence, as it worked just fine the next day and/or the next time I placed it in 4wd.
4hi/4lo light always lights up in the gauges as they should and as if everything is working normal.
So, IWE's? Actuators? Vacuum?

I just bought this truck, a 2004 F150 Lariat, 4x4. It is in great shape, but seems to have a problem with the cruise control... I have been reading different things, but one thing I just discovered is that with the key ON, the brake pedal NOT depressed, I can shift the truck into gear. I know that's not right. So am I needing that switch above the brake pedal and will that fix my cruise control as well?

I'm working on a 04 F150 Fx4, cruise control is not working at all, but I can't seem to find the cruise module under the hood. I haven't worked on this year before so I'm not familiar with the layout under the hood. Also, is there a brake pressure sensor on the 04 (new style) like there is on the '03 and below style? there isn't one on my master cylinder, so where would it be? Where to look? Why the cruise wouldn't be working?

View 3 RepliesFord F-150 (2004-2008) :: Headlights Stopped Working
I was having a problem where my headlights were turning off every time I would turn my directional signals on (2004 F150). Started out that it was mainly during left turns, but recently it affected right turns as well. Did a bit of google research as well as asking a mechanic to take a look at it while he was repairing something else, and all signs seemed to point to a bad multifunction switch.
So I replaced the mfs, and now my headlights don't work at all. The high beams work when I flash them, but not when I click them on fully. The parking lights work as well as the directionals. Took the truck into Ford and they are saying the headlight switch is bad. Does this sound right? After blowing $100+ on a mfs I'd hate to drop on a headlight switch only to find that it too, doesn't fix the problem. Not to mention NOBODY around here seems to carry the switch in stock. I checked the 2 fuses for the headlights and they looked fine.
