I have an 85 Pininfarina Spider. My drivers side window will go down but not up. I removed the door panel and reversed the wires and the window will go up. I know the motor is good and the switch is new. I talked to Vick auto and he said that I could put a reverse polarity relay in the lines to fix the problem. I obtained the parts which was easy but inserting the relays into the line isn't an easy fix. Before I go to all of that trouble does anyone have another suggestion. My next thought was to run a new wire from the back of the switch to the motor to see if it fixes the problem. Anyone else experienced this problem? Do you have a fix? Thanks in advance for your input
