Hello all, I purchased my '90 mustang about 2 months ago. The driver side window controls do not work, but the passenger side window relay works. So i can roll my passenger window up and down with my passenger side control but i cannot roll that same window down with my driver side control, i took off the arm rest to see if it was just unplugged but no luck it seem to be plugged all the way in at the actual button itself and at the connector inside the arm rest. the next thing i was thinking of doing is taking the connector with the pins out and using some sand paper to clean the connecting pins. I'm curious if anyone can shed light on my issue, any information would be greatly appreciated!
