Passenger window *This One has me stumped 🤔 *
I’m no stranger to replacing window clips I’ve also replaced the front passenger window regulator / actuator twice Don’t you love it when your passenger thinks your door is from the grandmas Cadillac? 🙄 I’ll get to the point, New clips, new regulator/ actuator it’s been rolled up for a few months… I’m getting back to getting it all back together The window won’t roll down… Not with the driver side controls or the passenger control. I did save the OEM Bosch motor year ago, and sure enough it works! Well kinda… only IN ONE direction! Drivers switches, passenger switch I reversed the wiring and sure enough it rolls down, and will reverse the Bosch motor. So WTF 🤬 could possibly be going on!? Thanks in advance PC |

Module or wiring issues? Is there anything else that doesn't work?

That is a common problem for the driver side so I suspect it’s the same issue. Water gets inside and corrodes the traces of the circuitboard.
Open it up and take some pictures I know exactly what traces to do on the driver side are out on the passenger side as well Sent from my iPhone using Tapatalk Pro

The main mystery is…
The Driver side switch (for the passenger window) And the Passenger side switch (for the passenger window) BOTH work to roll the Passenger window UP Also both work to roll the window down when I reverse the wiring. On my voltmeter I get about 13.89 (rolling up position) And a brief - (neg) then nothing (rolling down position) All the other switches on the drivers side work fine for rolling the other 3 windows up and down |

I need to see the back of that circuit board. Figure out how that pulls out of the plastic case. It's very similar to the driver's side master control. They use a bidirectional relay and I suspect a control trace for the relay is corroded away.
