a/c Can anyone give me a clue or solution to my a/c problem? When I start the car, the a/c blows cold air. This lasts for anywhere between 3minutes to 30 minutes.

Asked by Apr 22, 2011 at 04:50 PM about the 2005 Kia Optima

Question type: Maintenance & Repair

Then it blows neutral air ( not hot, not cold).  If I turn the car off for about 5 minutes, then it works again.  My mechanic has replaced a valve, put coolant in it, and checked the pressure.  He thinks there is a glitch in the computer.  Anyone else with this problem?   Judy

Sounds like you have a air flow problem. At a stop your fan should kick on, If it doesnt get it replaced. But before you do that when you start your car does it seem the ac keeps on kicking on and off? If thats the case then your low a freon.

Thanks. The freon is full - had it checked first and filled. I will check out the fan, but mechanic says its ok. A/C just stops working - for no reason I can associate with it. Just while I am driving - blows great cold air for a bit, then just "neutral" air. Computer problem? It's Texas and it's hot outside!
