Interesting electrical issue...
So my passenger side power window doesn't work nor does the power lock switch. On the driver side the window and lock switch work fine, BUT IT DOES NOT operate the passenger side window. The pass side lock work's fine.
At first I thought it was the motor, so I took the door panel off and before I pulled the motor, I applied power directly to the motor's connector. It work's! Both up and down fine.
So then I thought maybe the switch, so just pulled the driver side one and switched them around, nothing. Then I put all the switches in the known working window (the driver side spot) and they all work, up and down.
Then I noticed something.. If I power the window directly and get it down, both side's will raise the window, but won't lower it.
Fuses seem to be good, kinda stumped here...

Just guessing here, but does it work like this?
You energize one terminal to make it go down, and another to raise it?
If it does then you might have a wiring issue between your passenger switch and the motor.
I'd try using a meter on the motor to see what happens when you hit the switches. The appropriate teminals for down and up should do the same thing when the switch is pushed in that direction.
One other thought is that the switch doesn't drive it directly, but through a relay -- I really don't know if that's the case. If there is a relay, that's another thing to check.
ood Luck,

FYI - The power window motors are of the reversing polarity type. By that I mean that to go up you apply +12 to one wire and ground to the other. To go down you would switch the wires. That is what the window switches do. If it goes in any direction then your wiring is ok because both wires on the motor are used for both directions. Just today I removed the power window switch on the passenger side of my 93 F150 and disassembled it so that I could clean it with contact cleaner. Worked perfectly. The power door locks work the same way also. The power door locks are actually motors with a shaft that screws in or out when the motor spins.

I was having same problem. I replaced motor worked a few days then started the same thing again. Put the old one back in and work awhile. Took both switches apart and spayed electronic cleaner on them. No problems since then.
