Air suspension not working

Unread post by Tsbirge » Wed Apr 03, 2013 5:21 pm

Replaced rear air springs. Air compressor will not activate. No codes showing up through the switch, can activate rear inflator switch, compressor will run but air bags still will not inflate. Please advise

You probably replaced the rear air springs because they were leaking, right? Well, what happens is that the compressor basically loses all function after constantly trying to re-inflate leaking bags. Being able to turn it on by the inflator switch makes no difference, and it will usually not set any codes for this problem.

You're going to have to replace the compressor. Make sure all air lines and fittings are tight and in the proper positions when you install the new compressor.
