I just got a 2003 Tahoe LT. The unlock button on the driver side does nothing.

Here are the facts:
1. The driver side unlock button does nothing.
2. The driver side lock button works fine.
3. The passenger side lock and unlock button works fine, including locking / unlocking the driver side door.
4. The FOB lock / unlock works fine, including locking / unlocking the driver's side door.
5. The auto locking / unlocking works fine, including on the driver's side.

Best I can tell, the only thing that doesn't work is the unlock side of the lock / unlock rocker switch on the driver's side.

What I've done.
1. Swapped the master control switch on the driver side door with a new AC Delco one. Same problem.
2. Reversed the lock / unlock relays on the driver side door. No difference.

Any ideas?

Thanks for your help.

 

Welcome to the forum.
Check the unlock wire between the switch and the lock.

 

it's one of the most common questions we get here.
