I was having a similar issue with the driver side power features not working (windows, locks, etc.). The passenger side works just like you said, and the fuses are good. If shorting of the battery cables does not reboot the system, what would be the next step to fixing the issue?

Welcome to 2CarPros.

You lost me on shorting the battery terminals. Have you checked to see if there is power to the switch? Do any of the functions work? Have you removed the door panel to make sure nothing has come disconnected?

Let me know.

I'm sorry. When I asked the question I was going off of your response to another question. We have a 2004 suburban LT and has to disconnect the battery terminal to fix some wiring on the brake lights. Once it was complete and the battery was reconnected, we could roll the driver window up. None of the driver side switch functions work (windows, mirrors, power locks) but the rest of the power locks and windows were fine. We checked to make sure no wires were accidentally pulled or damaged and didn't find anything. The fuses all seemed to be good also. We tried what you suggested to another person on here about disconnecting the battery cables and touching them together to try and "reboot" the controls. No luck. Could it maybe be the lt door circuit breaker?

Welcome back:

No problem. So, all the windows work but the driver's side? Also, none of the other options on the same switch works?

Interestingly, all power to all doors goes through the main switch. Have you checked to make sure nothing has come apart in the door?

There is a coupler fuses I need you to check at the left of the instrument panel. See the attached pictures.

Let me know what you find.

We replaced the lt door cb because none of the fuses were bad. The ddm looked good but we replaced it anyway and it worked! Thank you for your advice.
