How to fix my cargo door so it will lock on 2007 H3 Hummer?

Asked by Nov 26, 2014 at 03:36 PM about the 2007 Hummer H3

Question type: Maintenance & Repair

All the doors will lock except the rear
cargo door.

1 Answer


Take the tailgate inner door pannel off and see if the lock actuator plug is still plugged in. If so see if you have power running to it when the lock/unlock buttons are pushed. If you have power while it's plugged in the the lock actuator is bad and need to be replaced.
