Window issue
 

I have a 1985 911 Cabriolet, the passenger windo operates form both switches, the mirrors work, but the driver side window does not. Is this a relay issue as the harness seem to be good

Try switching out switches from passenger side to drivers side..

Be sure you have the wires going to the right spades on the back of the driver side switch. There are wiring diagrams and pictures of wire colors folks have posted. Helps to have a multi-meter and check the switch per the diagram at each pin. My bet is that one (two) of the wires are in the wrong place on the driver's switch.

Here's a link to a thread with pictures of the pin-out for each switch...
