1999 GMC Jimmy Q&A
1999 GMC Jimmy Question: Driver side power window will not work, how do you check for bad switch?
Make sure you don't have the lock on it!!! Very simple and you don't need a mechanic if that's the case. That just happened to me. If not then they need to take the entire door apart to get the window motor out and test it's connections to see if it's gone bad. (my shop did this before figuring out it was just the button down that cuts power to the motor...) - orangeyellowdog
There is no child lock for the drivers window. Who ever told you it is most unlikely the motor is WRONG. - EXPERTEC

I have a 2004 gmc sierra, had the same problem, all other windows worked fine, turned out to be the harness connection inside the fuse box, pushed it in tight and works fine. - Blakthorn
