Chevy Tahoe - Door Locks, Alarm & Other Strange Problems!

South Main Auto Repair · 20 October 2026

In this video, I'm working on a customer's 2017 Chevy Tahoe that's having some pretty strange issues with one of the rear doors. Sometimes it locks and unlocks, sometimes it doesn't. Sometimes you can open it from the inside, and other times you can't. Oh, and just to make things more interesting, sometimes opening the door sets off the alarm!

With all these intermittent problems, there's no telling what we're going to find. Come along as we do a little troubleshooting and see if we can get to the bottom of this one!
