What makes the compressor turn on so air will be sent to the air suspension? I use to hear the air compressor kick on when I would turn the ignition key on and sometimes while I was inside the vehicle while it was running. I dont hear the air compressor kick on anymore and of course Im having problems with the rear of the vehicle not raising up anymore. The air compressor does turn on when I manually turn it on at the manual switch located in the rear compressor - and I am able to use the air fitting in the rear compartment to inflate air into my tires when I need to.
