It sounds like you are low on freon and the system needs to be recharged.If you are low on freon your ac system has a leak.

2004 Yukon Denali purchased 30 days ago. I've never heard the compressor kick on nor has it leveled when I put a boat trailer on it. The strange thing is there is no warning on the dash and rides well


if dealer could not find out problem would seek second opinion -any codes was compressor tested and is operating --was level switches tested and not rusted and see if system was disconnected and bypassed-that the shocks are the air ride/level option not the standard shock dealer should have been able to tell you this --system is not hard to diagnose for them on a lift and or hooked up -

Where is the air compressor for the ride control on 06 gmc denail


Ride control compressors burn up because of leaking air line or shocks. Replacing compressor won't last long if you have a leak. Most of these units are mounted under floor near rear axle.

Why do I get a rattling sound in the rear of my 2004 GMC Yukon Denali XL every time I start it?


It is the compressor to the shocks. It hapens when the shock has a leak. It's called air ride system. it's very annoying disconnect the power going to the motor behind the driver rear wheel or fix the air leak

Why does it sound like an air compressor is always running?


air shocks, they get cold and go down on air or you have a slight leak in the lines. it is normal for the compressor to come on when you start the car. RT

No cold air. compressor works for seconds and shuts off


Replace the compressor, if it quits running after a few seconds, it is more than likely your compressor causing the problems

4wd wont work on 1999 chevy tracker but front drive shaft is turning?


The locking hub control system is not engaging properly. On the 99 Tracker this is a compressed air system that consists of an air pump (compressor), electrical wiring to power and control the air pump, and air hoses that lead to an actuator inside the front differential housing. If there is a leak in the system the PCM will run the air pump for 10 seconds and then shut off, and your propeller shaft can turn all day long, but the front axles will remain free floating. Turn on your key, not your engine, and engage four wheel high. Go listen near the passenger front bumper for the air compressor. If you hear it, then the compressor control and the compressor itself are likely fine. If it shuts off after 10 secs or so, and your 4WD light isn’t on, the PCM timed out the compressor out and shut the compressor off to protect it. You will have to find the leak and fix it. If you are lucky, it’s the air line leading to the front differential; and not the air line inside the differential housing, or the air bladder in the locking actuator, which also resides inside the font diff. If the compressor shuts off and the 4WD light is on (this means the PCM did not shut the air compressor off due to timeout, so the pressure switch read 5-7 psi and the pump shut itself off), you likely don’t have a leak, and something mechanical has the actuator hung up inside the front differential. Lastly if you don't hear the compressor run at all, you either have a faulty compressor, or some sort of wiring problem in that circuit.....it could be as simple as a blown fuse. Good luck.

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!
