I was just cruising down the road with my ac on, it was blowing cold air working really good. All of a sudden it was blowing hot air. As I got to investigating it I found that the compressor clutch is not cycling on and off. It won’t charge me on at all. I tried using contact cleaner to clean the two electrical connections on the compressor and no help!

Does anyone know what the problem might be and how to fix it?

could be the pressure switch or cycle switch,usually near accumalator.check volts at clutch plug.
