On your 2003 yukon denali, the air ride compressor is located on the driver side rear frame rail on the outboard side, near the fuel filler neck and behind the left rear wheel. Hope this helps!

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.

2003 Yukon Denali has Service ride Control Warning..wat to do?


Hi Jose:
The first place to start is to have Ride Control Module scanned for trouble codes, this requires a high end scan tool. Most common problem is the air compressor in the rear or a height sensor. Here is how the system works.

Automatic Level Control Description and Operation
The RTD system is bi-state real time damping system. The Suspension Control module controls the suspension damper solenoids and suspension position sensors, along with parts of the automatic level control (ALC) system and electronic variable orifice (EVO) power steering system.

The Automatic Level Control system consists of the following:
• Suspension Control Module
• Compressor/Leveling Module
- Air Pressure Sensor
- Exhaust Solenoid
• Compressor Motor Relay

The objective of the Automatic Level Control System is to provide constant ride height at all load conditions. The Suspension Control module monitors body-to-wheel height, and vehicle speed.

The Suspension Control module will use the rear body-to-wheel displacements and vehicle speed inputs to keep the rear trim height of the vehicle at its desired level.

The electronic suspension control (ESC) system is bi-state real time damping system. The ESC module controls the suspension damper solenoids and suspension position sensors, along with parts of the automatic level control (ALC) system, if 1500 series.

The ESC system consists of the following:
• The ESC module
• The compressor/leveling module, if 1500 series
- The air pressure sensor, if 1500 series
- The exhaust solenoid, if 1500 series
• The compressor motor relay, if 1500 series
• The steering handwheel speed/position sensor
• The suspension damper solenoids
• The suspension position sensors

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.

How do iservice ride control


this is for the Auto Level for the rear axle,in "most cases" the compressor is bad, and one or both rear shocks leak air. What happens is a shock leaks air and the compressor tries to keep it up, but runs so long that it burns up or is worn out from running too much. plan on at least $1000.00. but have it checked out, YMMV

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.

2003 GMC Yukon XL Denali Service Ride control info


leaking suspension air bags is the most common cause, but the system can be tested for trouble codes, I suggest u do so, only the dealer can do this, but guessing about what the problem is can get very expensive very fast.

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!
