Ford F-150 - 1997-2003 :: 2000 - No Air Blowing Through Heater
My 00 f-150 is not blowing air through the heater I replaced heater core and the temp door I had same problem before work done I did not see an issue when apart but no vacuum or electric to test when apart. The only thing that changes when I move selector for vent floor and defrost I do get a little better flow when on vent. My feet get cold and defrost is not working well if I put hand on defrost I feel warm air but 3-4" away when on floor; I feel nothing anything at all fan seems fine.

This problem is on my son's 2000 F-250 5.4. It's into October and my son tells me he has no heat coming out of his vents. I figure it has to be the control valve that should be in the heater hose lines. Could be jammed closed or a vacuum line has come off the pot that controls the open close cycle. We open the hood and nowhere can we see a coolant control flow valve. It is so tight and dark under all that mess of wires, intake, air conditioner lines and whatever.
Just where should we be looking for the valve. Also it could be the vacuum line is unplugged on the dash, behind the warm/cool selector. And even there is a possibility that some doofus has removed something. He bought the truck this summer. So to get us on the right path, where we start looking for the flow control valve?
Ford F-150 - 1997-2003 :: 1998 - Heater Blows Cold?
1998 F150 step side, 4.6 V-8 automatic, 176,000 miles -
Heater begins to blow heat as the engine warms up - heat gauge moves up to normal level - running at speed, suddenly the heater blows all cold, the heat gauge pegs to total hot - the oil light comes on, the engine begins to miss - stop the truck, shut off the motor, wait 10 seconds, start back up and all is normal and away I go. Heater working just fine. Gauges are just fine. Have checked the hoses when it pegged to hot, and they are just warm just as if everything is normal.
Problem is intermittent.
Have changed radiator reservoir cap, thermostat, made sure fluid level and mixture is correct - what else to check? Computer issue?

I have 1998 F-150 and the heater core was replaced 18 months ago. All was going well until about 2 weeks ago I noticed under heavy acceleration I would smell antifreeze. The smell would clear up and would not re appear for a day or so. Finally the other day when it was 8 outside I got in the truck and got about 5 miles from the house started up a hill and it was like a fog machine was mounted behind my dash the windows fogged up almost immediately so I figured great the core went bad again. Now the temperature has warmed up the last couple of days and there is nothing no fog in the cab the heater works fine just an occasional slight smell of antifreeze. Before I go through the trouble of tearing out the dash is there anything I should check I already checked the connections on the firewall and they were fine.
View 5 RepliesFord F-150 - 1997-2003 :: Heater Is Blowing Lukewarm Air After About 20 - 30 Minutes Of Normal Driving
I'm driving a 2000 F150 with the Triton V8 5.4L.
My check engine light came on the other night while heading home. I went to Auto Zone and had them scan it and it came back with the P0125 error code.
My guess is that the thermostat is faulty because my heater is blowing lukewarm air after about 20-30 minutes of normal driving and I would expect the air to be much warmer so I'm thinking that the engine is not getting up to normal operating temperature.
I understand that this can be bad for fuel economy and such, but my question is it safe to drive?
I had planned on hunting up in the hills tomorrow all day and just want to know if this could cause any damage?
Here's a picture of what my cluster looks like after running for about 30 minutes.

We got our first taste of fall weather in Houston this weekend, and with it I've discovered a new problem with my truck. After the engine was up to temp, I noticed that the heater would blow cold air any time I sat at idle. If you rev up the rpm's to 1500-2000, you can feel the air start to get warm again. I'm guessing this means my heater core needs to be backflushed.

View 5 RepliesFord F-150 - 1997-2003 :: 1998 - A/C Blowing Cold Via Floor Or Defrost Vents?
1998 F150 XLT 4.6l automatic,,,
Drove the truck on a trip the other day, about 650 miles with a loaded 5x8 trailer in tow. A/C started acting weird. When the truck was on level ground, or going down hill, the A/C was fine. Cold air coming out the correct dash vents. As soon as I started up hill, or put the truck under strain of acceleration, the A/C would stop blowing out the dash vents and would start coming out the floor or defrost vents, or just not come out anywhere.
When I turned the A/C off and just used the vent setting, it would do the same thing with the fresh air. I guessing this has something to do with my vacuum lines, somewhere. What I should be looking for and where?
Ford F-150 - 1997-2003 :: 1998 2WD - Rear Axle Vent Tube Blowing Oil
Ok, I have a 98 F150 XLT, standard cab, 8 ft. bed, 2WD with limited slip - if any of that makes a difference.
The rear axle vent tube is literally blowing oil out the top, where it's loosely connected to the bed. It does this every few weeks. I pulled the hose and ran a rifle cleaning rod down it to make sure it wasn't plugged ... it wasn't.
It seems like it's building up pressure somewhere, then blowing all at once, but why?

View 2 RepliesPassat (B5) :: 2003 V6 Overheating - Leak At Hose On Driver Side Of Heater Box
I have in the last 5000 miles had the timing belt changed and at same time the usual other item - water pump, Thermostat etc,, Engine has 155k on it.
I have had overheating issues that I thought was related to the viscous fan clutch and replaced that (it was bad) and the issue of overheating now just take longer to happen.
I have bled the coolant system and have good hot air out with heater - engine warms up within 1/2 mile of house. I am running right now Prestome all color antifreeze as it was overheating and and loosing liquid as a result.
In trouble shooting yesterday I find that when it now overheats it is leaking at the heater hose on drivers side of heater box. I have repositioned hose and clamp after bleeding it and it still overheats and with pressure build up leaks at this location - this happens when moving or when stationary.
With heat coming from heater box (both hoses get hot) and both fans working would this be bad thermostat? (again have heat) or a bad water pump?

View 13 RepliesFord F-150 - 1997-2003 :: 2000 5.4L - Top Radiator Hose Comes Off
I have a 2000 F150 with 5.4 L motor. The last two trips I have had the top radiator hose come off while under heavy load (pulling a long hill) after 5 hours of driving. So far I have flushed the radiator, checked the thermostat, and refilled with G05 Gold and distilled water 60/40 ratio. I do not hear any gurgling in the heater core. Heater seems to work great.
The stock temp gauge shows it right in the middle range between Hot and cold, right before it blows the hose off. I have replaced top and bottom hoses and put new stainless steel clamps at all end except the top, where I am using the OEM clamp that came with the truck. I thought about replacing the top clamp as well but did not want to blow out my radiator, if in fact it is developing high pressure.
Do these clamps get weak with time? Should I use a vacuum attachment on the fill/overflow tank to remove all air before refilling?

this winter i have found that my truck's heater core isn't flowing, meaning i have hot on the upper hose and the lower is luke warm and there is no heat while running down the road. I have changed the t-stat and the heater core and radiator are new as of four years ago. last year i could roast a chicken with the heat. i also have no pressure in the radiator hose at all, engine runs at normal temp, no over heat situation and i don't smell any loss of antifreeze.
