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.

Well, I guess at least a welcome to the forum is needed. Lots of threads here about faulty ground wires causing "Ghost" problems.

Welcome to the Forum.

Folks here are willing to share their experiences and perspectives, and offer advice when asked.

I agree with the above suggestions regarding first checking your ground connections to ensure that they are all tight and secure.

I would still check the harness that feeds through the hole up top just because it doesn't do it only when you open the hatch doesn't mean it couldn't be worn or frayed in the same place.

The 07 had some electrical gremlins. You could also do a Google search. Good luck and hope you get it repaired.
