The driver side control panel doesn't work. No locks, no windows, no side mirror adjustment, no light on the window lock. I popped off the control unit and unplugged and replugged everything back in. Everything works fine on all the other doors.
Any ideas?

Thanks!!

 

I had to replace that in my 1999 GMC Sierra and also have a 2012 2500hd acting up. Sometimes the windows won't work until I shift back to park. Not good... Ebay and Amazon most likely have replacements and they're easy to replace. Sometimes it's just a solder point that breaks in module.
