Check the fuses first, then follow the power. They have more than 1 fuse for power windows.

Which Relay/Fuse controls the power windows?


Did you check for battery voltage at the switch , with a volt meter before you replaced the main driver door switch ? Maybe you'll want to take this to pro ,instead of just replacing parts !

Passenger electric window will go down but not up


The master switch is the one located on the drivers side. If this switch has a malfunction it can rob power from the passenger side causing the problem you have. If the regulator/motor are in working order and you know the passenger switch is ok then that could be the problem. Another couple of possible problems could be a broken wire in the harness traveling from the car to the door (inside the rubber protective boot or a weak window motor (1990 is pretty old for a motor of that type.

Reverse your test light connector, connect it to power so you can check for ground at window motor, flip switch up or down should have ground at both wire's while flipping switch to up or down, more then likely your not going to have ground at the up position, do same test at harness before passenger door switch if no ground master switch bad.

Passenger side window will not go back up


No.The drivers master power switch is probably bad.YOu will have to perform a test on the three other switches on the master. Check for power and ground when you push each putton.If the master switch fails the test you need a new master switch.

Failed power window


I'd bet on a broken wire in the harness going to the drivers door. I suggest the drivers door because it is used the most often. You can pull the master switch and check the wires for continuity to the harness just under the dash at the fuse box, after removing the lower dash trim panel. Sometimes you can gently pull on the wires of the door harness from under the dash and one will pull right out. Thats how I found mine.
