2005 GMC Yukon 1500 Denali XL Air ride Issue

[mnmtwi]

I have an issue with my air ride on my Yukon Denali. Here are the details.

 

New rear air shocks approx. 1 year ago, no problems after replacement.

 

At some point compressor stopped running----pulled battery to reset with no luck, compressor clicks but will not run.

 

No error on dashboard

 

One shock is fully extended (driver rear), other shock is completely lowered (passenger rear) Both bags are soft.

 

I have pulled all connections from shocks and replaced the complete compressor and still having same issue.

 

Not sure what to check next and how to check. Thanks in advance!!

I'm going to say a circuit problem to a leveling sensor. There has to be a DTC set in the suspension control module
