I recently bought a '99 Suburban, and the power windows all work form the driver's panel, but the front passenger window doesn't work from the passenger panel. The window switch also contains the lock switch, which does work. I don't like just replacing items until the problem is solved, but I do think it is the switch.
Any ideas?
Thanks,

Welcome to the forum
Its possible its the drivers side switch that is causing it as its where all the power/signals are distributed from. You will need to pull the switches and check for power, might also try taking the switches apart and cleaning the contacts in them...its free place to start

 

It turned out to be the driver's side switch panel. Contact cleaner and an air compressor made it all better.

Thnks!
