Most of the time the condenser coil is dirty and needs to be washed out. with it dirty the pressures are elevated and causes compressor to kick out on overload. try washing cond. coil first

My toyota corollas (2004 LE) a/c blows out cold air for 10 min and then starts blowing out warm/hot air. Filled up freon but it did not work.


Sounds like your HAVC pressure switch is going out cutting off prematurely or the system is overcharged and shutting off to prevent damage.

2005 sante fe a/c blows warm air when idling @ stop light - works ok at higher speeds


You need to recharge your a/c, and check its fuses. It's not blowing cold air at all, even when you are driving, because when you are driving it is blowing in the cooler moving air from outside your vehicle.

Our AC blows very cold air, but after awhile it starts blowing warm to hot air. What do you think it is?


It is most likely the compressor. When the A/C starts blowing warm, Check the power cable to the compressor. If it has power, it is the compressor. If not, you will have to check the system to see where the power loss is.

A/C blows warm air


Have your a/c tech look at the pressures at an idle. It sounds like the condensing coil does'nt have enough airflow or the compressor is week. Another possible problem could be that the temp control door is'nt operating properly. Hope this helps. Good luck.
