hello all,

I recently had issues with my windows only working from the master switch and not their own panel. thanks to some help on here I was able to fix that by soldering the connection points. But a problem that has always persisted is that my rear driver door window will only go down, and won't roll up. Jumping the motor works, the door switch there works it just won't go up via the master switch or the switch on the panel. I've googled around and it seems like if there's an issue with the master switch then that will affect all the other windows. I checked the wires running through the door jamb and kick panel and they all seem intact... same with the wires running to the regulator at the problem door

Is a new master switch a possible fix? do I have to track each single wire for a fault? I don't know what to do -- I'm really at my wits end with this vehicle...

thank you!
