    I have a 2002 tundra I’m looking for the location for the window relay for the passenger side door. The window motor works, switch works, I can only think of a fuse or relay thats bad but I don’t know where the window relay is located. The main fuse box under the hood on the driver side has a power lock relay but I don’t see one for power window relay. I need help!

    If the driver window lock sw is bad(dirty=open) or depressed(=open), the gnd signal does not make it to passenger window circuit(motor) !

    If there isn’t a window relay in the fuse is good, what else could it be? The motor works in the switch works so I don’t know what else to check.

    Are you able to control up/down of pass window with driver side master sw ?
    As mentioned in post above, is the driver side window lock switch accidently depressed ?

    A bad master sw will cause passenger window not to work.

    Just curious, how did you test motor and switch….bench test ?

    Mine refused to work because of a broken power window master switch.

    I'm confused. The OP says the motor is working. If you can hear the motor running then it is probably a broken window regulator. Or am I reading the post wrong?

    I’m Figuring he tested the motor and it worked.

    typically if the regulator breaks the window falls

    Oh ok. My bad, you're right the window does usually fall when reg. breaks.

    It's according to how he tested switch and/or motor....hence the question I posed for him in above post. You can bench test a motor or apply voltage and gnd to wire harness at door to check motor if one suspects switch. As Dan said and I alluded to earlier, a master switch can cause a passenger window switch not to work.

    My window regulator was crudded up and got stuck in the tracks. Window motor shutoff when I tried to raise the window. Wouldn't go up or down and the motor seemed to be non-op. I took the door card off and cleaned and lubed the track. Motor came right back to life when not in a bind. Works great now.
