Any rear window experts out there?
Bought a new to me 97 4runner last month and the rear power window doesn't work. I spent the weekend Searching and troubleshooting, but couldn't find a solution.
Troubleshooting so far:
- window lock is off
- rear wiper and 3rd break light works.
- looked for broken wires and couldn't find any
- truck didn't come with the master key so can't test the rear lock up/down
- When I press down on the rear window switch nothing happens
- pressing up gets a click (in the relay?)
- took the back panned off and used a battery to jump the motor: it works!
- the up switch will raise the window after I manually (jump) it down
- took the switch apart, ohm meter told me that the down wasn't working, tweaked the switch and its working now
- the up and down when tested with the ohm meter work
- tested the switch plug. Found 5 pins. + and - for the light, + for the up, + for the down and a shared - for up and down
- the + for up has 11.5v
- the - for down has only 2.3v
I'm thinking that my problem is the 2.3v for the down circuit? I don't know what would cause this? Bad relay perhaps? Anyone want to break out the multimeter and test the #5 pin (one in the middle) at the switch end for voltage?
Any ideas on how the switch and or electrical system works for for the rear window? I don't have a lot of experience with electrical stuff, so I can only assume that it's so type of voodoo going on in the blue electrical box in the back door.
Thanks for help or insight that you can provide!
