Ok, i have done a lot of troubleshooting before making this post, but i am at a loss. I have a 1995 Chevy Blazer 4.3L 4 door 4WD LT Edition. My problem started about a week ago where in the middle of the night, my brake lights decided to turn on and not go back off. I have determined that the brake light switch is good, so i decided to go through my fuses. I pulled the PWR ACCY fuse (which known to me operates door locks, power mirrors, and driver's power seat) and BINGO lights turn off! But now when i brake, not only do my brake lights light up but also my reverse lights, and just for fun my car also unlocks all doors when braking as well. I have check all the grounds on the back half of my car and wanted to throw a post up here before i started digging into my dash. Any help would be greatly appreciated or at least a list of the known grounds going to these functions of the car and where they are located at. I'm pretty sure this is a grounding problem but if anyone has seen this before and might know another issue, i am open to any suggestions. Thanks!
