AC starts and then stops working
My ac will work for a while and then all of a sudden will stop blowing cold air. The compressor is running and the fans are working. Whats the problem?

Just serviced my own for similar reasons, after the recharge we found a leak in the condensor. Ordered a new one today and it's going in tomorrow. $160 and a few hours and we should be golden. Now I can chill the ***** soup, damn it was hot today.

have you or someone ever taken off the under dash panel on the driver's side? look below your ignition, lower there is a small square grill piece. check behind there to see if the wiring clip is connected or not. you should see some 10mm bolts holding in the bottom plastic cover with the light bulb built into it. To get the second piece off take off the ignition ring cover, then pull the ignition cover panel off. then a couple more rockes this being disconnected will cause the AC to not blow cold or hard.

You should do the a/c test on the climate control and report back. I belive its just to turn your ignition to on while holding the temp button and air/recirc button until your a/c cycles.
If you're getting cold air for a while then hot air (assume its blowing hot on both sides?) then just get a gauge from any auto parts stores and check your psi on the fill line. - 44psi should be what you read, if its lower or higher then you have to either get some r134 removed or get some refilled.
Worst case its just your servo motors (but then you'd be experiencing hot/cold air on either side) or your ambient temp sensor is going bad, or your compressor is telling you its going bad.

Starfyrels, I have a full motion w the servo & i went to an AC shop to have it check properly W the right freon & psi. I have a good feeling its a sensor but which one.
What does the "ambient" sensor do?

Yeah Sakataj, i read tht from a previous post you posted. I went to an AC shop where they did everything & properly charged the system(no leak). but now, the compressor comes on but no cold air. It was fine after i left the shop on Sat... however, since monday it blows straight hot air while the compressor is on. so, i will ck the ambient sensor like they previously mentioned, if not will take it back to the shop.
