A/C compressor disengages after 10 minutes - Toyota Nation Forum : Toyota Car and Truck Forums

I have an '05 corolla and the A/C works great for about 10 minutes then the compressor clutch disengages. I've tested the relay and it works, the low side pressure is about 35 psi in 85 degree weather. Any ideas on where I can troubleshoot? Thanks.

Does it actually start to blow hot air? The compressor should cycle on and off to prevent freezing. Does the light start to blink? (Or should that happen on the Corolla - I remember it did happen on my Camry when the compressor was seizing up.)

If it is indeed a malfunction, then maybe your compressor is seizing. If you are lucky, maybe only the belt is on too tight. A new compressor would be costly.
