Hello, I'm Cam. Please include all the details about your issue so I can accurately advise you. I cannot see your vehicle so please be detailed.

Do you hear any noise in the rear hatch when you do try to unlock it?

OK, HEre is what I suspect. This could be a bad actuator in there rear hatch.
Also possibly the wiring to the rear from the body.
It could be the relay itself or the bcm not commanding the relay. ARe you looking at ideas for taking it in or are you looking to diagnose it yourself?
Customer: replied 5 years ago.

I'm looking to diagnose myself. Will you tell me how I go about fixing it and checking each of your ideas as to what can be wrong.

Expert:  GM Tech (Cam) replied 5 years ago.
Ok, first we need a simple test light. You can get one for about 10 at a part store. Nothing fancy with LED's, just a light.

When you get it, test at the fuse for power when you try to activate the rear hatch.
Tell me if you get power there.
