So my issue is the a/c wont come on. Its clicking the compressor relay and fan relay on off on off but the compressor is not coming on. So far i pulled the charge and replaced the low pressure switch on the compressor and wiring plug as well. Recharged the system with the same issue. Its also reving the motor and diming the lights everytime it clicks on and pulseing the coolant fan. Ive unplugged the ac relay and coolant fan relay and does the same thing. It has a 1 year old compressor and new compressor relay. Only thing that will stop it is to unplug either the high pressure or low switch. Both switches are 2 wire so im assuming they are just open close? Any ideas on this?
