Customer Question

i had a service air suspension come on the dash and I replaced the level sensor and it went away. But the compressor wont level the hummer. When I have someone press the ride height button I can feel relay click but the compressor still doesnt turn on. If I remove the relay and run a wire between the 2 large pins the compressor kicks on. Not sure what is going on.

Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

In order to try and help you determine why your compressor is not running I need to know what year you working on as well as have you scanned the system and retrieved the fault code and or codes that should be setting when the suspension system fails. If you can get the scan done and post back with the fault code and or codes as your model year I will try and help you get this resolved.

04 Hummer, I had it scanned before and was told the left level sensor was bad. So I replaced it and the "service air suspension" went away on the dash. But the compressor still doesnt turn on.

Can you have it scanned again and see if there are nay fault codes setting and get me the actual codes?
