Ok, finally got out to work on the car today....

I disconnected the switch from the rear door and tried rolling down the window with the front switch and the fuse did not blow. Then I disconnected the front switch and tried rolling down the window with the rear switch and it still did not blow. In neither case did the window roll up or down though, as the window only rolls up and down if both switches are plugged in. The fuse also only blows if both switches are plugged in. And it seemed that the fuse only blew if the front switch was used.

So where should I look now? The wires going from the front switch to the rear switch?

Thanks,
David
