SOURCE: location of fuse box/panel for 2004 yukon denali xl

There are 2 fuse panels in the Denali.
One is a panel on the drivers side, its on the dash but facing the door.

The ohter is under the dash and above the pedals, this one is much tougher to access.

Your Owner's Manual should tell you where the fuses are that you need to access.

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!

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.

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

My 2001 yukon denali is saying serevice ride control what does that mean?


Seems like a common problem with these trucks. I thought I was the only one. I just posted this comment for someone who has a 2003.....I'm not an expert and not sure how widespread the warning message can be, but in my personal case: I have a 2001 Yukon Denali.....I have the same problem and have for many months. I took it in a few times and the GMC Dealership finally told me that It's the ride air bags. In my case they are leaking. Its not the same safety airbags in the front dash to prevent injury...but these models have air bags under the truck that automatically adjust to level when weight shift...you might hear the occasional sound coming from the back while driving or when more people are in your Denali. To me it sounds like a power tool. The Service tech told me it's not harful nor will it damage anything, but it costs about $2000 to fix, because they have to replace the whole thing. He said you may notice the sound coming on from the airbags more often because of this..because the system is working harder to adjust the weight due to the leak/loss in air. So occasionally for about a year...the light comes on....but it has done nothing else.

I hope this helps.

There isn't any fuel getting to my truck and it won't start


No fuel pressure indicates one of three problems. Fuse in fuse box, relay in relay box under the hood or fuel pump located in fuel tank.
