Start the car and ac, both fan and compressor are on, hot air. Leave it for 10 minutes, same thing. If I rev the engine high cold air start to come on, same if I start driving, really cold. I have a set of gauges but the low side gauge is bad so I hooked up one of those auto zone air charge connector and it shows it to be in the red, not at 150 but above 85. I connected the high side from my gauge set with both ends closed, opened the side where the port is and it shows 150psi. Also, not sure if related, the AC and RECIR buttons are always lit, you cannot turn them off if you press on them. I tried to scan for codes but it is not connecting to the hVAC module.
