I think the only thing you need to worry about, if doing just the module, is if yours has the dual compressors or single compressor. Then the module needs to come from the same.

 

if you tell me where it is, i can pull it off mine.
that is if it is not needed for something else.
i have done the spring conversion so my whole system is gone, but i am sure they didnt remove the computer (unless it is on the compressor setup)

 

Thank you for the offer. What year is yours, I believe my ECU was only fitted on 2005 and up? If you have an in-built tyre-inflator it won't work without the ECU.

No need to remove it as its a little tricky, if you look under the rear LHS of the truck you'll see the ECU (might have to give a wipe) you should be able to read the GM part number (see below)

 

All resolved now, replaced the AS compressor unit including the AS-Controller.

The old controller had died!

 

I might be interested in your system. I have a storage unit in Nashville that I need to pack up and bring out west anyway. Are you close to Nashville?

 

No. I'm 3.5 hours away. Near Knoxville Tennessee
