I have a 2002 Suburban LT with Autoride feature.

Rear shocks were leaking and compressor running more than usual. I replaced both rear shocks and now system won't work. I tested the compressor (12v directly to compressor) and it ran fine.
Checked the Fuse. All is good there.

Does anybody know where I go from here.

How do you test the various components with an Ohm Meter?? Is it possible??

Also, no computer codes being generated.

I performed a search and found alot of questions but very few answers.

Any help would be greatly appreciated.

 

Anybody ???

 

From what I have read today, it looks like there is some sort of switch on the wheelwell. I'm not sure how it engages, but it looks like there are two sensors and when the rear of the vehicle lowers it gets them close enough and turns on the compressor. Mine stopped working about 6 months ago. I'm going to check into it this weekend and I'll let you know. If you don't hear anything, shoot me a PM or an email and I'll tell you what I found.
