99 grand. Have read about wiring between door and body. They all look good. My issue is the driver side window quit working and the driver side lock switch won't lock, it will unlock if it is already locked. All other windows and mirrors work from the switch. Any suggestions? I'm thinking I will have to take the door apart but anything I should look for?

 

Ok. So had to go pick up my daughter and the lock switch was working. The window still isn't.

 

Sounds like it could be the window switch going bad on you, either that or you have a wiring issue.

 

If the switch is bad then I shouldn't be able to put any window down right? Only one not working is driver side, everything else working.

 

Turns out it was the motor. Just replaced the regulator and motor with a JY find for $27.00.
