I recently had the heater core replaced in my durango. Now my power doors locks will unlock the doors but will not lock the doors. It seems like everyone once in a while it will work and other times not. Could this be a grounding problem or something else going on?

Are all of the doors affected? Does the switch inside the vehicle work? Have you tried replacing the battery in the FOB? He may have inadvertently done something to the wiring to cause it...

The power lock wiring diagram is attached below

Have you checked for power to the main switch on the driver's door?
