rear window wont go up
My 93 4runner rear window wont go up. The console switch and rear key will both roll the window down but when you try to roll it up all you here a relay click behind the driver side taillight.

Inspect wiring. Check for sensing switches if in proper position. Disconnect connector from wiper assembly and see if it changes anything. That will eliminated doubt on wiper out of park sensor.

I think the latch shut sensors are working cause it beeps when i try to roll the window up when the tailgate is down. And the wiper sensor seems to be working if it will let the window roll down.The relay is clicking when I try to roll it up so I need to see if its putting out any power. I just didn't know if there was another safety switch somewhere.

, if you hear relay click whn u try to operate windows, then control circuit must be working, but something is keeping power from reaching the motor or motor is bad in one direction. Need schematic to be sure. U can also test motor off the truck.
Again, schematic wud help a lot. I can help with schematic IF u have a first-gen

I think there is two relays that control the motor. One for up, one for down. One or both can deteriorate and have poor flow across the contacts.
I pulled the relay that controls the window going up on mine and soldered on a new one. I just bought a relay with the same specs and form factor.
I replaced mine here in Australia with one of these from memory: http://au.rs-online.com/web/p/non-la...-relays/047658
The window control board behind the panel where you can hear the relay clicking from that has these relays soldered onto it. If you pull the panel and control board, then with a multimeter you can check what is going on.
