I was installing a new stereo and i forgot to disconnect the battery, needless to say there was a spark and now my security system no longer works, the doors lock but only when the car is on. also the dome lights and all inside courtesy lights no longer work, i have to manually lock the doors, and the clock always resets as well as the ac when the truck turns on and off. Please help!!!!!!! I have changed the ecm and bcm with no luck. checked all fuses but no luck.
