Without hooking up a manifold gauge set to check high and low side pressures it makes it much harder to diagnose. however air and or moisture in the system could cause this as well as a weak compressor. or a partially clogged thermostatic expansion valve. good luck and I hope this helps!!!

2008 Trailblazer Air Conditioner not cooling. blows warm air for the first few miles then cools. It has been recharged.


Philip, You may have to have a good tech, check,diagnose and estimate repair. Could be a few things causing poor AC, recheck your charge level,check your fan at the condenser, make sure the condenser isn't obstructed, compressor clutch could be faulty, system could be plugged with contaminates limiting refrigerant flow.You say the system has been recharged, was it done properly, if not system could be plugged. AC system should of had system checked for leaks,evacuated, flushed, new orifice tube, then recharged with proper quantities of oil and refrigerant. Check the attached links,instruction and guides, Good luck

AC blows hot air when I go over 60 miles per hour. Works fine otherwise.


Interesting question. The AC condensor is in front of the radiator, and the movement of the car (or the fan) cools the refrigerant.

This is not working normally. I'd suspect
a) the refrigerant level is low (ie a slow leak), fix is refilling it.
b) the compressor stops working at higher rpm. Various issues can cause this.

Have the system pressure checked at an AC shop. One QUICK and dirty way is to take off the AC hose HI pressure cap. Press the valve BRIEFLY. If you hear a sharp, loud noise of escaping pressure, the level is probably OK. If you hear a soft hissing sound, the pressure is low, and the refigerant has to be refilled.

My 2002 Expedition air conditioner will sometimes blow hot air and others cold air


I would check the following possibilities:
1. Is compressor clutch working? - You need to do this when the ac is blowing hot air only - locate compressor drive pulley on engine - rubber belt wraps around it. Start engine and set to max ac. When the ac is blowing hot air, look at the center of the compressor drive pulley using a good flash light - watch it for a while, it should be spinning with the pulley - this means the compressor is engaged. If not, the compressor is not engaged. If your ac is blowing hot air, then the compressor should be engaged and running (trying to cool). If it is not engaged, then your compressor clutch is probably going out. Could be low voltage to clutch, but more likely the clutch is worn out and only working some of the time. Note: if working normally, the compressor clutch will engage and disengage in cycles- but the air should always be cold. If clutch is bad, compressor would need to be replaced (sold as one unit). This is tricky to diagnose and could take some time - you need to do it when ac is blowing hot air but set to max cooling.

2. Low on refrigerant or refrigerant has moisture in it? If your ac blows cold initially after being off for a while, then heats up, and continues to regularly cycle back and forth between hot and cool air, then the system may be low on refrigerant or the refrigerant may have moisture in it that is freezing and restricting refrigerant flow. An a/c shop can check refrigerant level and even replace refrigerant if moisture is suspected.

Could be other issues, but I would start with these.

Good luck

this problem is caused by a defective air temperature control blend door actuator motor, it is about center of dadsh in air ducting, it moves the door that diverts air for cold from ac or hot from heater, you must remove the dash to repace it, about a 15 hour job fotr a home mechanic with a factory repair manual, nearly imposs without one.
