hi guys i have a 94 4runner.
Both rear windows have been giving me trouble. At first they would slow down a lot (sometimes stop) half way up.
Now, for the most part they don't even work. Sometimes they will go up but not down. I took the switches out and swapped them with a good switch and they still work intermitantly. I tested and it appears i still have power going to the window switch harness.
Could the problem be the switch with the drivers door master switch setup?
Does anyone know which terminals to connect directly to a battery to test the motor.

 

If you clean the master switch on the drivers door, it should help. it did with mine and even now mine still ****s up alot. my passenger window would not work at all unless there was some magic in the air (So never). i cleaned all the switchs out with compressed air that i use for the PC and some electical cleaner from GUNK and now only the master switch can work the windows. if the passenger uses it i have to do something to that switch to make it work.
