I would suspect the switch. I had a 1992 Transport (little brother to Silhouette) with exactly the same problem, I have the Hayes repair manual with schematics, and was eventually able to trace it to a broken (open circuit) tan wire from the rhs switch back to the drivers door. I never did find the break or bad connection, but was able to drive the window up by touching a ground wire to the tan wire terminal on the back of rhs switch. You can NOT leave the ground on or the drivers switch will short the +12v to ground and blow it. If you want more info, email me rob@syn.ca

There is only one fuse for all power windows. If only the passenger side window does not work, the problem is either with the passenger window switch or the motor on that window.
Your switch is bad or the window motor has gone out
Begin by removing the 1994 Chevy passenger side door panel. Remove the window motor wiring harness. Remove the window motor linkage. Remove the window motor retaining bolts. Reverse the process to install the new window motor.
The switch could be bad at the passenger seat. The switch could be bad at the passenger seat.
Remove the door panel then the motor. The window regulator is spring loaded and there are sharp edges inside the doors so be careful.
go to your local machanic
Check to see if you are getting power to the motor if so window motor is defective Could be open wire usually in the door jamb area
Bad motor? bad switch?
If it is just the passanger side don't bother with the fuses. the wiring does go thru the drivers side and then to the passanger side. Use a voltmeter at the passenger power window motor. If you get 12V to the motor it is probably bad. If you don't have 12V at the motor the wiring to it is probably bad. Make sure you didn't accidently turn off the passenger window switch at the drivers side door.
Hi .. To change the power window motor .. Remove the door shell of course You will see the motor for the window .. Unplug the power of course . The motor is actually riveted in so you need to drill out the rivets. Remove the old unit . Then install the new motor with self tapping screws . Plug in the power . Be sure to secure the window when you remove the motor so it doesn't fall. I have not done this yet but am about to embark soon and have done some research . Good luck ..
