so ive got an 87 4runner that i bought not to long ago and have been trying to fix up. and one of the issues im having is figuring out why the rear window does not work. press the switch and nothing. but at one point i disconnected the switch at its connector and jumped it with a wire and i was able to intermittently get the window to work.not sure how to go about diagnosing the issue any further. especially not having a wiring diagram. any help is appreciated.

 

Does it work with the key switch in the hatch??

These switches do go bad .

red/ yellow is up

green /yellow is down

blue /red is the common

then there are quiet a few safety switches.

the window lock

cover top switch

wiper retraction switch

back door lock switch (shows the hatch being closed)

any of these open will not allow the window to move.

It could just be a worn tired motor or things being dry from being unused.

 

The post #185 above this link https://www.yotatech.com/forums/f199...l#post51723243 has some info as well.

 

key doesnt work in any of the locks. but ill look into seeing if maybe its the removable top switch or something like that
