2004 Tahoe LT rear door lock issue

[rrwidow89]

I have a 2004 Tahoe LT. About 6 months ago I started having issues with the rear door locks refusing to unlock using either the driver side door controls or the key fob. You can manually unlock them. Ideas? Thanks in advance!

Can you hear any clicking from the door? Take the panel off and try the fob while having a look around.

Nope. There is no noise coming from either side when the remote or driver's door controls are activated...

Ok sounds like a power or switch issue. Pop the panel off and do the same. I believe the power comes from the wires under the sill plate.
