My passenger window stopped working, I have eliminated the motor and switch as the problem by systematically removing and replacing them. What else could could be wrong? Are there relays? If so, where are they located?

If both the passenger door and driver's door switch won't put the window up, it's either the fuse or the window motor (probably not the switch since they both stopped working at the same time). If it was working fine and all of a sudden stopped working, it's probably a fuse or relay. If it gradually got slower until it stopped, it's most likely the window motor.
Good luck

Motor burned out

Direct feed the motor from the vehicle battery, if it works then the fault is in the switch or the wiring, swop the switch with the passenger side switch and try that, that will eliminate a switch fault. 11.4 volts is low, what is battery voltage, should be the same a low voltage reading say's there is possibly high resistance somewhere (switch or a bad earth connection)

Try the switch in the door, as well as the one in the center console to eliminate the possibility of a bad switch. If the switch in the door, and the one in the center console both do not work -- then you probably have a bad window motor.

The relay operates all the windows. The drivers door switch is the master and has to be connected for the rest to work. It sounds like you have a bad motor or a bad connection on the motor in the drivers door.

It can be the switch or the motor, as long as it is getting power. If the switch at the door goes bad, the master switch may also not work, even though it still may be good, and vise versa. The switch goes bad more often then the motor. When the motor and track assembly go bad, you can usually hear the motor turning, but the window doesn't go up and down. Since you mentioned that it worked and stopped and worked again, though it still could be the motor, I would start with the switches. You can buy them on eBay for about half the cost you would pay at the dealer. If you have someone that can check things out a little, I would have then check for power to the motor and both switches. You can usually substitute a switch from another door to eliminate the possibility that that switch is bad. Hope this help. Good luck and have a nice evening. Peter

Window fuse's and relay's may be up under passenger side dash or behind glove box.
Drivers door window gets used the most so it could be the motor, window switch, relay or fuse.
Could also be a broken wire in the rubber boot going from the door to the body. You will have to eliminate each till you find the culprit.
The motor and the relay are the most likely to cause this problem. Try swapping the relay with a working window relay. If it still doesn't work, remove the door panel and remove the window motor.
Turn the motor shaft in both directions by hand several turns. Then plug the motor in and see if the switch will now run the motor. Sometimes thats all it takes to get it working again. I have had to do this with brand new motors. If voltage is not present at the motor connector, either a bad switch or a broken wire exsists. Make sure to check for voltage coming to that windows switch. Actually, GM use's a circuit breaker type relay for each window and one fuse for all the circuit breakers.

These are high current motors and you risk fire with any wiring error. Toyota just had a recall on these switches. Recommend replacing same with same, they are fairly simple, but take pictures as you disassemble. Be sure to lube the new switch with silicone. While at it, run canning paraffin (Or a candle) up and down the glides of all windows to make travel easier. .

I suggest replacing the switch on the passenger side. Chances are the switch is faulty by a back connection inside - switch is wore out - if it works every now and then.

Let me know if you need further assistance.

More than likely you have a bad switch. You can try to pry the switch apart and clean the contacts inside. Usually the passenger side switch is pretty inexpensive, around $25-$35. The switches get dirty inside from dirt or water dripping when it rains and the window is opened or if someone might have spilled something on it.
