a friend bought it at an auction said service air ride in cluster, found the fuse 62 missing under the hood. I thought wow that was easy compressor came on and it kept running and running until the rear end was at max height and kept running. went to relay and the module is continuously grounding it. unhooked relay and module checked for a short to ground found none. checked ride height sensors and the voltages are way off. I found the module above the spare tire like the fuel pump control modules are that fail left and right. the module was corroded and everything. could shake it and hear things moving around in there. have you guys run into this??
