Lock problem

[HDScottie]

2005 Yukon XL, the liftgate lock will not unlock after shifter is placed in PARK. Doesn't unlock even if lock/unlock button is pressed. Actuator has been replaced. Any suggestions?

if the actuator is trying to work it could just be a problem with the mechanical part of the lock in the latch. might just need some lubrication being its 15-16 yr old latch. if the actuator isnt doing anything you could have a wiring problem to the actuator. lastly the master could have an issue and isnt sending power to that lock actuator.

You say master. Are you referring to the master switch?

ah yes sorry gm vehicles tend to route everything through the drivers door switch block
