Air compressor for the autoride suspension. It will usually kick on a few seconds after starting to do a self test and/or inflate the rear shocks.Hi everyone,
I have a 2013 LTZ and when the ignition is ON, I hear this grinding noise coming from the rear end and it stops after 4 seconds. It sounds like something is engaging. Any ideas will be appreciated.
Thanks.Air compressor for the autoride suspension. It will usually kick on a few seconds after starting to do a self test and/or inflate the rear shocks.
Its located behind the drivers rear wheelwell. Next time, start the vehicle and get out and listen in that area for a few seconds and see if that's it.
