Hey Scotty! I need ur help bad! Just replaced the entire wiring harness in a 2002 trailblazer... but the interior lights and power locks only work when the key is in the ignition and in the on position... and when put into any other gear besides park the lights and power locks go out and will not work, along with the battery voltage dropping all the way down. I then have to press the ac or recirculate button and turn the fan on for The the lights and power locks to work while driving!!.. what do I do????

well, I'd assume the wiring was not hooked up right, get a wiring diagram and check. OR the BCM has been damaged, it controls all that stuff
