i have a ghost in my 07 yukon denali. My rear lights center flash on and off running or not its the same ones as the security ones rear only when you open the tailgate. but if flashes when it feels like it. it drains the batt overnight. i had the BCM flashed at the dealer. replaced the rear tail lights replaced the fuse block under the hood. no idea.
