Good Morning all,

I have a 2002 Suburban with the autoride and automatic leveling feature. Recently I noticed that my voltage meter was dropping for several seconds, lights would dim and heater fans would slow. At first I thought it might be my alternator but then it occured to me that I had not heard my auto-leveling compressor in several days. This unit always kicks on within 30 seconds of starting the engine but not lately. Looking a bit closer, I noticed that when I start the truck and the voltage meter shows a drain occuring, I can hear a clicking in the rear end where the compressor is located. So, I'm figuring that it is attempting to kick on but can't. So I'm left wondering.... Is there a way to disengage this so it doesn't try to turn-on and does anyone out there have any experience troubleshooting this feature. I suspect that with the crazy weather we have here in the northeast that moisture likely got into the system and froze causing something not-to-good to happen. We've had a recent string of warmer weather and I can't believe that there is ice loaded up...but it still doesn't work.

any help would be greatly appreciated.

Thanks in advance

There is a maxi fuse in the fuse block under the hood you can pull
