This is how I wired them.http://forums.pelicanparts.com/uploa...1646518959.jpg

maybe bad connection. Some corrosion, may need contact cleaner. Also, looked at the wiring again and found 2 wires switched.

Does anyone have the window switch wire connection diagram for using the old style Bosch chrome bezel 4 contact window switches?

Looks like I corrected the wiring. Had 2 wires switched on the passenger side. The fuse is blown.
Would be great if someone could double check my wiring before I replace the fuse. Not real sure, can’t see real well.

Fixed. Replaced the fuse and windows work. Cleaning the contacts before the panels go back in.

Got my "86 911 Targa back after having some other works done to find that the window on the drivers side stopped working.
To be fair the glass had popped out and was down in the door so I should have been more sceptical
After pulling the mechanism checking the motor , which worked, and putting it all back together it still refused to work as it should.
It was very odd.
after a few hours troubleshooting it turned out to be that when the car was in the shop they crossed the 4 and 5 wires to the switch.
The pictures and diagrams on this thread were perfect to find that problem

Couldn’t agree more!! I’ve messed around with these little buggers more than once! Always wondered if the 964 or 993 platform had a more elegant solution.

HI everyone, just reviving this old thread. I've got an issue with the window going up when i press down and down when I press up. I repaired my window regulator and the only thing I can think I've done is mixed the position of the wires in the photo above.
There are 2 red and blue wires at the top of the switch and two red and blue wires at tbe bottom. Does it matter if the positions get mixed up, because they're the same colours?

Pull the switch out, twist it around and re-install. I don't believe there is a top or bottom on these.

When I pulled mine out of the door the unused terminal was at the bottom and someone else posted a few posts up with photos that there's is also on the bottom.
Is this incorrect. When I press up my window goes down, but I could have sworn when I pulled out the switch the unused terminal was on the bottom.
