Question about GMC Yukon
The Bose system is set up differently from other radios...each speaker has its own seperate power amp, so you have two connections to each speaker, the 12v power, and the low level signal...you can use a front speaker to plug into the rear wires and if it plays, you need a new speaker/amp...if it doesn't, you're missing power or signal for that channel...

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.

it has to do with your air ride suspension best bet is take it to the dealer there is probably a problem with a level sensor. hope this helps you
