My '94 SR5 4Runner window will not roll down!
I had this problem when I first got the truck 4 years ago. I fixed it by replacing the rear-window drive motor and the rear-window ECU relays.
The strange thing is that it will roll up...just not down. I'm pretty good with mechanics and electronics, but this has me baffled. Here are the facts:
- The rear-window rolls up perfectly. No resistance since the mech assy. is clean and well lubricated.
- It does not roll down.
- When I try to roll it down from the rear door key or the front control I can hear a relay click from the rear-window ECU.
- I've replaced the rear-window ECU with a known good one. Nothing.
- I've verified the drive motor spins in both directions by removing and testing it.
- I beat my head against the bumper and cried...nothing.
If anyone has any ideas please offer them up because I'm close to losing my marbles.
Cheers,
Richard.
