Probably this topic might have been covered but I thought I would still share with you guys.

Problems: Windows (both rears and passenger) dont go up or down using driver master switch. Windows go up and down no problem using their own respective switches.


Time needed: 30mins or less

Tools/materials needed: Flat head screw drivers, aluminum foil paper

Step 1: Remove and disconnect the master switch from the door, pry it with a small flat head and it should pop right out.

Step 2: Remove the wood trim from by unscrewing the 3 silver bolts

Step 3: You should see 6 black bolts (sorry i forgot if there were 4 or 6 of them), remove them too and that should bring you to the circuit board (take extra caution when separating the buttons from the board because there is a total of 5 little springs in there that might fly away) . Look at Pic 1, the red circle indicates what a good contact point should look like. Now look at Pic 2, you should see a pretty burnt out contact point in red circle, and that's the reason why the windows arent responding to your command because there' no conductivity

Step 4: cut a tiny piece of aluminum foil paper and place it in between the burnt contact point and the top button. Now the path for conduction should re-establish once the top is pressed down.

Step 5: put everything back together and now everything should be back in working condition.


Basically I cannot open or close the windows using the master switch and I was about to spend $80 on an used switch from ebay but before I sent the money I decided to open it up and give it a try see if I can keep the $80 in my wallet.

Again this little fix only applies to burnt contact point inside the circuit board.

Hope it helps, thanks

That might be helpful as I reconstruct my driver's side door card.

Thanks.

Looks good man. I might have to do this on my supra. The masterswitch doesnt roll down the passenger window but it could roll it up :S

Good post. My only question is couldn't the burnt contacts get cleaned up?

Well to me it's easier just slide in a pc of aluminum paper.
ofcourse you can try cleaning it.

I cleaned mine with a tiny "point file"
