My rear left window goes down without a problem but won't go back up. I can roll it down with both the drivers master switch and the switch on the rear left door itself but neither of them can roll ot back up.
Is this a good question?

the wire going to the up part of the switch is the problem. the motor takes at least 3 wires. this way it can reverse the polarity to change direction. trace that wire and check it has power when depressed for both directions with a volt meter or 12v light pen.
