The works intermittently. It will be cooling normally and then the compressor will cycle off and wont come back on for 20 or 30 minutes. I checked the pressure with compressor not running and it was 190 PSI on both high and low side. I also replaced the relay but this did not solve the problem. I thought maybe the thermistor was bad but if I change set point to call for heat the air gets hot. Checked to see if voltage to clutch and there was not any. Not sure what to check next.

Hello,

It sounds like the HVAC controller is going out and needs to cool before it will work again. To be sure here is a guide to check for power and signal to the fuses and relays with the air conditioner wiring diagrams so you can see how the system works:

Here is the fuse panel and relay locations and how to change out the HVAC controller. Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.
