Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hello, my name is Bobby. Thank you for the question. Can you tell me if you can get the door open? Do all of the other doors work fine?
Thank you. Just so I make sure that I understand completely, when you try pulling the door open it will not open like it is locked. I am assuming that the lace pulls the lock lever up to unlock it so you can open it?
That does make sense. When you press the lock and unlock do you hear the lock actuator making noise in the door?
Thanks. It sounds like the lock actuator in the door is bad. Do you have a voltage meter to run some tests?
So that I know where to begin, do you have the door panel off and can you easily access the actuators in the door?
This is a power lftgate also, correct?
Ok. On the rear lock actuator you need to locate the connection with the tan and gray wire. Disconnect the connector and place your meter between the two terminals. When trying to lock and unlock the gate see if there is a voltage reading on the meter. If not then the PCB relay in the fuse box under the dash may be the problem.
Unfortunately I do not have a diagram of the actuator itself. All I have is the wiring diagram for it.
When you press the liftgate switch do you get power at the light blue wire?
