Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hi Rob, I am Cam. Can you tell me what year your Tahoe is?
Ok the issue with your liftgate not opening electronically is the liftgate actuator. Inside the actuator is a nylon gear and it's surely stripped. Sadly the gear is not available on its own. The actuator as an assembly must be replaced. It takes about an hour and the actuator is about 500. This is not related to soldering the tab back on.
