Air leveling system module location

[Dammen8]

Can anyone help point me in the right direction as to where the module is located in a 2014 yukon denali?

I have a feeling that mine is having issues because it very intermittently with run the compress and when it does run, it only runs for a second up to maybe 3 seconds. Thanks for any help

When does the compressor run for 3-5 seconds? On startup? If yes, that is the normal operation of the system.

The module is located on the under side of the truck behind the spare tire. It is rectangular in shape.

Feel the bladders on both rear shocks. Do they feel firm?

It rarely runs on startup anymore, I put my car trailer on the other day and it never ran, it just let the vehicle sag. I have owned this vehicle for 35000 miles and yes it is supposed to do a test run at startup but sadly 95 percent of the time it does not and if it does happen to, the run time is only a second or two..

Honestly I'd delete it and get springs and struts. Less headache

If you have a quality bi-directional scanner, you can easily troubleshoot the issue and find the root cause.

It's controlled by the electronic suspension control module and it's located above the spare tire on the driver's side.

Keep the factory suspension setup if you can - it's excellent and reliable. My guess is you have a failing compressor and at least one leaky air shock. New OEM shocks and compressor are available for a reasonable cost on rockauto.com. The Dorman compressor is also a good quality part - I have one on my '07 and it's been flawless.

Any new info? The symptoms your referring to go along with a leaking air bag. Soapy water in a squirt bottle will verify. Either diagnose and replace one or both or pull the fuse to the air compressor before it burns up from overheating.
