Ford A/C :: 2006 F150 - Warm Air Blowing While Idling?


Sep 20, 2007

Having problems with the A/C on F150 2006 or newer. It blows warm air while idling. I have taken mine to 2 different dealerships had Ford engineers down and no one can seem to find the problem. I love Ford vehicles but I can't handle this in the these hot summers.

Ford F-150 (2004-2008) :: 2006 - Rough Idling When Warm And Dying At Stops Or In Reverse

My brother's 5.4 has been rough idling and dying at stops and in reverse for a few weeks now. Today it threw a code and he finally had me look at it and it's a P0345 code. I was thinking cam phasers possibly, but I didn't think that would cause a code to throw. Also, all I hear about cam phasers is that it makes the truck sound like a diesel, but his when it's about to die sounds like the engine is about to drop out the bottom of the engine bay. Really rough, REALLY loud knocking, etc... What we should be looking at replacing to get this thing back into shape?

Sonata NF (2006-10) :: A/C Blowing Warm - Compressor Oil

My 2006 Sonata GLS 3.3 A/C started blowing warm, so I checked all the fuses and they were good. Swapped the relays and still nothing so I check the wire to the compressor and it was reading 14v. This would lead me to believe the a/c clutch is bad, I didn't want to replace just the clutch incase my compressor craps out on me later on so I'm just replacing the whole thing now. My questions is how much oil does a new compressor need?

Sonata NF (2006-10) :: AC Blowing Warm Not Cooling

Was just on a trip (about 200 miles or so each way) and the AC worked just fine.

Car has sat for a few days unused.....when I used it to day, the AC blows warm...doesnt cool at all.

I hooked up a gauge to the low pressure side and the pressure reads very high (in the red zone of the gauge).....

Cant tell if the compressor is kicking on or not when the car is running...

Car is 600 miles out of warranty (of course).

Gmc - Envoy :: 2006 - AC Slow To Cool Down And Blowing Warm Air For Several Minutes

Two weeks ago A/C was slow to cool down on and blowing warm air for several minutes; works fine since then. One week ago, check engine light came on. At the dealership now, they say it the check engine light is for the clutch heater and this would also relate to problem with a/c not cooling properly. Waiting to hear what repairs will cost. Is this OK to continue driving? What exactly is going on? Does this part need to be replaced? Should we just tape over the icon on the instrument panel to avoid looking at the pesky light?

Lexus GS 2006-11 :: Heater Was Blowing Cold At Idle And Warm When Driving

2007 GS 350 109,500 miles. My heater was blowing cold at idle and warm when driving so I took it to dealer. To my surprise, dealer says its a blown head gasket. No other symptoms. No white smoke, no smells, no warning lights on dash, and running fine. Just had VVT gear recall done last week.

Fortunately I have Lexus extended warranty good thru 125k miles and Feb 2014. I do my own maintenance (plugs, oil changes etc). Have records for all. But have not done coolant change (due at 100k).

Lexus GS 2006-11 :: Heater Blowing Cold At Idle, Warm When Revving / Driving

My '06 GS450h has developed a fault where the heater blows cold at idle and low revs but blows warm when driving or revving the engine at a standstill. The coolant hasn't dropped at all and the car never goes above halfway on the temp gauge. Its starting to get frustrating now the cold weather has set in and temps dropping! Long journeys are ok as at high speeds it stays warm but short journeys are uncomfortable!

I just had a feel of the rad hoses and hoses that go into the matrix (engine side of bulk head) and matrix hoses feel warm (both of them), the top hose to the rad is warm but not hot and bottom hose is cold suggesting the stat hasn't opened yet. Its cold outside so getting the car up to temp is quite difficult without a long drive (rush hour at the mo).

Still I just had the car parked on the drive and cranked the heater up to max and held the accelerator for a while and super warm air blows out. The engine cuts back out as "normal operating temp" has been reached for battery mode and then the heater goes cool again! Still the bottom radiator hose is cool and top hose not massively warm. It has never overheated thus far and I drive 150miles a day back and forth to Reading from Cheltenham 4 nights a week.

Only thing I can think of is a sticky thermostat or water pump not operating sufficiently enough to circulate the water? Its getting colder and short trips where it used to blow warm air nice and quickly (within 3-5miles) are becoming unpleasant!

Ford - F150 :: 2010 - Dies While Idling

It was a chilly morning for North Texas, in low 20's this morning. I started my truck in the driveway driveway, as I do any morning when it cold out, then retreated back the house to grab my coffee before hitting the road to work. This morning was different, the engine had stalled out but the battery still had the lights and radio on. Any thoughts on this aside from the usual guesses of cylinder, fuel pump and purge valve?

Prius (Gen 2) :: A/C Blowing Warm And Middle Vents Not Blowing Any Air?

I've recently purchased a 2007 Prius and I just noticed few days go that A/C blows warm air (weather was fair when I bought it and I can't remember if it really worked or not then) and middle vents do not blow any air. I'm not sure if two problems are connected but I do want to get both fixed without spending $$$ at the dealership. Where can I start?

Ford A/C :: 1997 F150 - Heater Only Blows Warm Air?

I have a 1997 ford f 150 lariat with the 4.6 v8 and my engine had a piston slap so I replaced the engine with a used one and I put a new water pump on the engine. My problem is the heater does not get hot and it only gets warm when I get on the freeway and the rpms stay steady for a bit. but when i idle it just blows cool air. the heat door works cause I can turn it to cold air when I'm on the freeway and i just replaced the thermostat so I don't believe its that. It weird because the heater worked fine before I changed out the engine so i cant figure it out. the only thing i can think of is the water pump is bad out of the box. Could it be the belt or does spacing on the water pump have something to do with it. nothing is leaking.

Ford - F150 :: Battery Warning Light Came On When Idling

Battery warning light came on a couple of times when driving to work in my 2000 F-150. I had thought that the instrument lights had looked dim for a couple of days. The warning light was only when the truck was idling and the warning went off as the truck was moving.

Ford Transmission :: 1999 F150 - Slipping In First When Warm / Pump Is Leaking

1999 F150, 4.2L v6, 180K miles, 2WD. Trans is flaring (slipping) in first when warm and was told the pump is leaking too. This truck has easy use (no big towing or hard use) and when it did it the second time, we parked it. I do not want to have anything fail and really damage things inside. We dropped the pan and changed the filter and filled it with fresh Motorcraft fluid. No change.

Ford Fuel System :: 1986 F150 Idling Rough / Leaking Injectors?

I have an 86 F150 that is idling rough. It used to cut out on me until I replaced the fuel pressure regulator. I have read in other posts that the problem for my rough idle could be leaking injectors. When I replaced the regulator I found a bad injector. My question is that if I check my fuel pressure, with the new regulator, would the only way I would lose pressure be that my injectors are leaking?
