Air Suspension not coming on

[Civcomm]

The compressor on my 2006 Yukon Denali air suspension system hasn't come on for a few months. No lights or warnings have come on about it. I've tried to look at the fuses and relays but didn't get beyond the fuses. Any ideas?

If the fuses are ok either the compressor is dead or it’s not getting the signal to turn on. When you turn the key on nothing happens? Climb under and check the connections. It may just be time for a new one.

a bad or burnt out compressor does not typically throw a code. Often what happens is the shocks have developed a air leak and the compressor has ran so many times it just burns out. even though they have a timer to turn them off as they are for intermittent use only.
you need a tech2 to check it out, or have a diagnostic done, or manually bypass the relay and/or fire up the parts cannon.
you can look under the truck and visually inspect the shocks if they are visibly blown out then that is your first clue.
