What could cause the air con to occasionally not run? The air con guy just fixed a slow leak and regassed. He checked compressor relay, pressure switch, a/c thermostat, and some other things. He reckons all is good on the a/c components. When the air con decides to not run, he just shorts one of the pins on compressor relay and it fires up straight away. His best guess is there is an error from the engine ecu that causes it to cut the a/c occasionally, maybe some engine sensor playing up.
