I have 1700 miles on my truck and the A/C cycles between cold and warm air. I have taken it to 2 Ford dealers and they agree there is something wrong but their tests are apparently up to Ford specs. They logged complaints with Ford and they were told this was by design with the new trucks and it was normal for the compressor to constantly cycle. New 2013??
View 2 RepliesI can't seem to get the engine temp to middle range on the marker, but yet my heater blows "to me" hot air. Even while sitting in idle for extended amounts of time I cannot get it to "operating" temperature. I would think if my thermostat was stuck open my heater would blow either cold or slightly warm air. I have the 5.4L engine with knn air filter and no cats.
View 14 RepliesI have a 1999 F250 7.3 Diesel and my AC isn't working properly. On Max AC as you're driving it would be ok and then it would be warm and then cold and then warm and then cold and so on. I've noticed that the clutch stays engaged as well. I've never seen it disengage. The freon is at the level it needs to be. Then just a few days ago, if you have it on Max and High the air disappears from the vents and you hear a noise somewhere in the dash on the passenger side. I think something might have come off?? What's wrong with my AC with it going from cold to warm constantly? I heard that maybe clutch has too big of a gap?? I have almost 200,000 miles on it.
View 6 RepliesI am the proud owner of a 2002 F250 Super Duty 4x4, which has 158K miles on it. I live in South Florida and use the truck as my daily driver and also from trips up into the Blue Ridge Mountains.
Recently, I noticed that when I have the A/C on it blows nice and cold for about 15 minutes, but then the air gets really warm. I had the system checked and the Freon levels are right where they should be. A bit of experimenting reveals that if I turn off the A/C for about 10 or 15 minutes after it starts to blow warm air, the systems blows cool air as it is supposed to.
Therefore, I suspect that something is freezing under the hood and preventing the system from operating properly. Since A/C is pretty well essential for us in south Florida, this is a problem, when I have the family or customers in the truck.

AC will blow cold, then shift to blowing warm, muggy air, then back to cold. Seems to be some relationship with throttle movement. Cruising steady ac seems normal. Multiple throttle shifts in changing traffic seems to trigger the warm air. Once accelerate back to normal cruise, can feel clutch/compressor shift and blows cold again.
Any ideas? I have read a possible cause can be the ac clutch can wear and need to remove spacers? Is this a DIY job? What about the ac clutch relay switch? On reading an online repair manual, seems that the clutch is magnetic, and if no battery power to clutch, it removes itself from compressor?
Just had an EGR delete kit installed. Any relationship to this and ac problem?
Its a 2001 f250 with a 5,4. I just recently put a new shot block in it, the short block is a svt short block for an 01 lightning. every thing off old motor went on new svt block just fine, and it drop in just fine. only it will not warm up i let it run for 45 min the other day and on the gauge it would not come past the c. and i do believe the gauge to be accurate because the heat in the cab sucks and the top rad hose is just warm, not as hot as it should be. I've already put 2 new thermostats in it so I don't believe that to be the issue either.
View 14 Replies2004 F250 V10, runs good until it warms up whether it's hot or cold outside. While on freeway, it really shakes while cruising, but of you get in the gas enough for a kick down, seems to be pretty smooth. I've changed the coils, and 9 plugs (one wouldn't budge, but the others I took out looked fine) to no effect. Where else should I look? Also, no CEL, and no codes, which seems odd as bad as it feels...

View 1 RepliesSunday I bought a 2001 f250/5.4 to replace my 91 f250. I didnt drive it yesterday, but this morning on my drive to work the heater was very weak, it seemed to blow warm for the most part, but was barely pushing air even on high. I flipped it over to A/C to see if it blew any harder and it did. Does the blower motor need replace? if so why does the AC blow harder than the heater?

Heater core issue:
Heat is not very warm after engine is fully up to temp. Would like to back flush the heater core without damaging or making it leak. How should I do this safely?
Secondly, if I do make it leak, how hard is it to change out?
I have a 2006 Ford F-250 5.4l the symptoms are when it's warm it has half power and it will stall at idle. What I have done with the truck is.
New cam phasers

I cleaned throttle body with brake cleaner ... Scanned it after a 15 min ride of having to use 2 feet to drive it. The engine codes that came up are p0022 iacv short to ground and p1000 readiness test not complete. I also got p1804 4 wheel drive high indicator circuit failure p1808 4 wheel drive low indicator circuit failure .... Not sure what else to try.
2002 - f250... I originally posted this issue in July of '03. Nothing has changed.
1. At max ac, regardless of how hot it is, the ac clutch cycles due to low pressure once the cabin temp reaches about 78 degrees. This is not acceptable or expected in my opinion.
2. I have run extensive tests, done this for years, and the conclusion is that there is too much pressure drop in the evaporator. I'm seeing 5-7 psi drop measured using a Fluke digital temp probe, insulating the probe tip around the pipe. Compare outlet of orifice tube several as far away from orifice as possible and comparing to outlet temp of evaporator where it comes out of the plastic shrowd. Convert temp to pressure.
I've seen many posts over the years of people not happy with '99 to '04 ford truck ac operation at cruising speed. I have confirmed that the compressor is cycling way too much to cool the cab down. I even ran an experiment where I completely blocked the condensor to raise the head pressure and the compressor still cycked at 1500 rpm's with the cab above 75 degrees on a 90+ degree day.
My next step is to blow out the evaporator and see how much oil and junk I get out of it. I'm also considering taking the evaporator out and trimming the rubber gasket that is around it. It is blocking about an inch of the coil face all the way around.
My conclusion still is that the evaporator just isn't loading up enough as if it's partially clogged. There is only about 2 psi drop between the outlet of the evaporator and the compressor.
The compressor cuts out at 21 psi so the low pressure cutout switch is working properly.
What should I use to flush the evaporator out? Will mineral spirits do it as long as I blow it out real well and make sure I get all of it out? Also wondering if I should blow out the condensor thinking maybe there is something clogging it up.
In spite of some folks on this forum saying it is normal for the compressor to cycle at cruising speed, that is a correct statement depending on many factors. In my case, the cycling is not normal or expected. I have also tried:
1. VOV
2. Larger orifice
3. 14 oz charge over what the sticker says
20 06 F350 6.0l ... Recently noticed when my climate control selector switch is on the off position, the a/c vacuum pump cycles for a few seconds then stops, then cycles, then stops.. Does this until it's changed to a different setting. Pulled the connector behind the selector and plugged the black hose and it stopped. Re-connected it and could hear site leaking so I kinked the white hose and it stopped. I have also lost my MAX a/c that is now defaulting to defrost. Is there a part number just got the hose selector, or a way to fix the existing one?

View 5 RepliesMy 2013 F-250 Super-Duty periodically won't start or come out of park. I have tried the ignition trick of tuning it to first position but with no luck. Sometimes I can see the light for the indicating light for being in park flashing on and off rapidly and manage to get it into neutral to start. It appears to be completely random. I potentially happens when I drive it for longer periods or do frequent stops around town.

When it's cold out it won't start at all I have to use starting fluid but once started it will start right back up. Did the plugs fuel filter cleaned the intake and sensors still have a problem plenty of fuel pressure plenty of cranking amps brand new battery and Alternator. It just cranks and cranks when it's warm out fires right up. Runs smooth no lack of power or misfire no codes are being thrown also.
View 14 RepliesI have a 2011 F250 with ac problems. When you start it in the morning and turn the ac on it only takes a small amount of time for the air to start cooling. If you turn the truck off then start it again after driving to town the ac blows hot air out up to 4 minutes (yes I timed it) before it starts cooling. I took it to a local repair shop and the first time they said it only had half the freon it needed. The charged it and off I went. Same problem. The second time they informed me the fan clutch was not engaging and replaced it. I picked it up and the first time it was turned off and back on it had the same problem. I am scheduled to take it back to the same repair shop on Monday.

I've removed the mirror from the vehicle but am not sure how to get to the inner motors without breaking something.
I just bought a used 2013 F-250 4x4 and it came with the snow plow pkg. heavy duty front springs. I love the truck, but won't be plowing with it, and I don't need the rough ride (and don't like the look of the front end higher than the rear)
How hard is it to swap out the front coil springs and replace them with the "regular" ones?
