Question about 2005 GMC Yukon Xl Denali
I have a 2007 Yukon Xl Denali with a self-leveling rear air shocks. They are shot, but the other thing is that I think that the air compressor is not working anymore either.
How can I check whether the compressor is still working?
There's a lever that connects the driver-side rear shock to the Automatic Level Control module (the air compressor and the ride-height sensor). Disconnect the lever from the shock and rotate it up and hold it. The compressor should kick in when you hold in place after a few seconds. If it doesn't kick in, make sure your fuses and relays are good. Otherwise, you may have a failed ALC module/burned out air compressor (from the shocks being shot). After you replace the shocks (and after you recouped from the heart attack you had when you shelled out $500+ for each shock), replace the ALC module/compressor (it's all one unit), and test it - it should kick on when you rotate the lever up again.
Figure about $350 for the ALC module from your dealer, and make sure the part numbers match! Your truck came with an upgraded ALC module from the 2001-2004 module, which were prone to water damage.

VERY COMMON FOR COMPRESSOR TO SEIZE UP BECAUSE OF ITS LOCATION... VERY EXPENSIVE FROM THE DEALER..500.00 , ARNOTT INDUSTRIES HAS AN AFFORDABLE AFTERMARKET FOR AROUND 150.00

There is a large fuse under the hood in the fuse box that is blown.
