SOURCE: 2004 yukon xl denali self-leveling rear air shocks

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.

Good luck!

SOURCE: 02 yukon denali security light stays on will not

Several GM products, including the Chevrolet Impala and Malibu, the Oldsmobile Alero, the Pontiac Grand Prix, and Saturn Ion, have issues with the Security light coming on. This is many times an indication of a failing Body Control Module (BCM). Initially, the Security light will come on then go off, progressing to a constant on light, before the car will refuse to start. Other symptoms may include erratic action of electronics, a clicking sound coming from the glove box, and the air conditioning failing to blow cold air. I recommend a shop that specializes in the electronic systems of vehicles to diagnosis and make the necessary repairs. They should keep the car until they replicate the symptoms described. A new BCM from GM should cost about $230; plan on another $200 for them to diagnose the problem, replace the unit, and program the new unit. The dealers quote between $700 and $1,100 for the same repair. My experience and the experiences I have read on the internet, indicate the new BCM should last only about a year.

probably because snow chains come off and tear stuff up, studded tires would be the only alternative that I can think of
