Bravada electrical problems

Figured I'd try a post here on the Blazer forum, with more chance for help. My '96 Bravada is having some weird electrical problems again. Upon starting the truck, the door locks lock, then unlock, then the rear hatch pops. In the past, I've been unable to turn off interior lights, as well, leading to me removing bulbs. Rear window switches work once in a great while. Just way too many electrical problems. Any advice, besides starting from scratch with wiring?

Under the back of the front seats, unplug the blue & black connectors and see if your troubles disappear. This would indicate a short in the power lumbar adjustment circuit...had the same problem in my '97 Bravada.
