I was bombing around in the red baron this weekend (1984 euro 300D, 4-spd with euro headlights and small bumpers) and my windows went crazy on me.
It was hilarious. As I would raise the drivers side window, the passenger side would open and visa versa. I could only get one closed and drove home that way.
I tried to uncross the wires connecting to the switches and was surprised that the wires seem to cross connect to each other. And there sure are a lot of them.
I know it's an easy fix, but it was beyond my skill and patience and it was getting to be miller time, so I garaged the beast .
