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.

Thanks. Mark
