air conditioner

sounds like a leak in the system somewere

 

Have you cleaned the condensor, sounds like its freezing up.

 

Have you had an a/c shop check it out for you or just doing yourself? Had the same problem but it was the expansion valve and you have had that replaced.

 

If the compressor is running and engine fan cycling, feel the a/c lines under the passenger door. Is the line with low side test port nice and cold? Did it quit working all of a sudden, or does it work and then die out?

 

Could it be that the clutches in the compressor are worn and it is not working properly.

 

Do you know if it has an "APADS" module on it? It is usually mounted on the firewall on the drivers side near the coolant tank. It will be a small block with a red and green LED on it.

 

Only other thing I could think of is the low pressure switch. Need to clean between the condenser and radiator. Or the filter in the orifice tube could be stopped up. Have you had dye put into the system to see if it is leaking anywhere? Or it could even be the belt slipping. Just let us know what is the problem when you get it fixed. As I asked before are you having an actual AC shop looking at it or are you doing it yourself?
