My passenger side window will not go down with the driver or passenger side switch. Any ideas on why, and what I need to fix/replace? I appreciate any help

Yeah, push your window lock button on the driver's side.

ARG! DTN! You should have sent him on a fuse hunt under the dash and had him remove his door panels to check connections and the works!

Muffler belts are a common cause of window failure as well. Have you checked the power window fluid lately?

There's no fuse that I know of which controls just the passenger window... Could be the switch, muffler belt, power window fluid, window regulator or either switch, or associated wiring.
