tail gate will not unlock
tail gate will not unlock on 2006 Cadillac Escalade
Have you been able to find out what the problem was with the tailgate?
If all the other doors lock and unlock, it's a good possibility that the solenoid for the lock on the rear hatch is bad. It has to be replaced as a whole assembly which will coast around $200. It's a pretty easy fix. I replaced mine a few weeks ago. Only took about thirty minutes.
