Rear window on Toyota 4Runner won't operate up or down

I cant open my2003 Toyota 4runner dikies, can anybody help m

rear window issue not rolling down?, take your rear window wiper blade and push up to the docking position. Then try the window. The wiper is electrically inline with the window relay. If it is not all the way up (sagging) then your window will not roll down. Hope this helps. Also, the relay board that operate rear window defog, and up/down is located drivers side behind the front seat behind the plastic trim. Next to the fuse box there are two circute breakers,in the center of the two breakers is a small hole take a tooth pick and push into the hole to reset the breaker,if I beleive the rear window breaker is nearest to the fuse box?? this should do the trick.

The rear window motor is on the way out, have it replaced. Soon helping it won't work and if down you won't be able to close it.

try seeing if u got power to the switches by pulling switches up and check with test light if u have power then window motor is out

Likely, is electrical. The switch is relatively primitive and could be a loose connection there or on the motor itself. I've commonly run into the wiring shorting where it enters the tailgate. Thats obviously not going to be easy to reach with the window up, but you can remove the panel from inside the back and get to the motor and all. Best bet is to expose te wires to the switch and see if they are still in circuit with an ohmmeter. If they are, the motor is likely bad or jammed, if not...you have to find the short somewhere. Hope this helps

Probably a broken wire where they run into your tail gate, or a loose ground.

toyota's are prone to wiring rot. a Local toyota dealer has told me (with the same problem) to chop the middle of the pannel off for the tailgate to get into the wiring. the connectors may have rotted off. if you find a solution, let me know.

I suspect that the back door ECU (the relay box that you speak of) is bad.
Unfortunatly common.
Here is how you check:
With the Key On, you should have 12 VDC in the Solid YELLOW wire going into the box.
Also, You should have power in the solid BLUE wire going into the box.
Operating the switches should transmit power to the BLUE with RED trace, and the VIOLEt with WHITE tracer.
If you have the right power as described abobe, the box is indeed bad. This is a dealer item only, cannot buy one at the local parts store. Sorry. Hope this helps.

check the window shield wiper in the right position, you must put it into the clamp.
