Yes...a bad master (DS switch) will cause problems with both windows. Even if the passenger switch is fine. Everything goes thru the DS switch first. Find a buddy with a 1g and swap out the switches on both sides (One at a time until you find it). Then you'll know for next time. These cars typically don't have wiring issues unless some redneck cut into something.

There are 2 wires per motor. Switching to another direction reverses the polarity. Also, looking at the circuit shows there is 1 window relay located right above the interior fuse box. But right after the relay the wire splits into 2 individual wires the feed each switch with power.

PS relay feed wires is pin #6 which is a blue with a black stripe. DS is a solid blue wire and pin #5 at master switch. Check any ground connections in the door. Let us know.
