2003 Hummer H2 V8 All Wheel Drive Automatic 85000 miles
Recently my alarm quit working. About the same time, my passenger front door power window, lock and mirror quit working. Within a week I noticed that the rear of my Hummer started sagging and the compressor has not kicked in to level the truck. I was told that the body control module was starting to fail. Is there a way for a backyard mechanic to troubleshoot this issue. I've built steetrods from the ground up but I don't want to waste time and money at the dealer unless I have to.
