Hope this might help someone. I have Firestone Air Bags and the Air Lift 72000 Wireless controller with compressor. The other day I tried to add some air to the airbags and got a COM ING message on the remote. For some reason I thought this meant connecting to the compressor. After it not working I called Air Lift technical help and was told that message means the compressor is not working. To troubleshoot I should connect the compressor directly to a 12 volt source. I connected the compressor to the battery and it worked fine. I called Tech help back and they were of no help and I suggested it might be the relay??? and I was told that was a possibility. I was told the relay is a standard GM 30 amp relay. I went to the local NAPA store and bought a 30 amp GM relay with 5 connections and replaced the relay. (only 4 wires are used). I tried the system and it is working fine now.
The moral is tech help sometimes doesn't have a clue. Air Lift does not sell parts to you (at least in this case) and sometimes you are better off trouble shooting it yourself. Posting this as a possible help to others who might have the same problem.
