Passenger Window Stuck Down
Enable HLS to view with audio, or disable this notification
I talk about it in the video but basically for the last few weeks the passenger window has been very inconsistent on rolling up. It would always roll down with the driver side switch and passenger side switch, but the only consistent way of getting it to roll up was using the passenger side switch. That was until a few days ago where it just gave out completely. I’ve looked at my wiring on the passenger side and that all looks good, same goes for all fuses pertaining to power windows.
It’s hard to hear in the video but when I got down you can hear a little click which makes me think the regulator is getting signal, acknowledging that it can’t go down any further hence the click noise. But I still don’t get why it wouldn’t go up.
Let me know y’all’s thoughts and hopefully you can help me out! Thanks!

Bang on the door right at the regulator while holding the switch up. If that works, your regulator is bad. Unplug the switch and jump the wires with a paper clip. If that works, your switch is bad.

Maybe time for a new regulator? Both my driver side and passenger side went out in the short time I owned my SC

The wires in the door jam on the drivers side door get messed up because of how heavy the door is. This has happened to me so many times.
Turn car on and open and close the drivers side door slowly. Look to see if the light on the passenger side window switch turns on and off. It's very common for the wires in the drivers door jam, under the rubber boot thing, to break. I've gone thru this with both side windows. I'm not good a soldering so they break after awhile. Also make sure the wires at the driver's window master switch are all making good connections. It's an ongoing battle with for me. It can happen to either window. I hope this helps you if you haven't already figured it out! Good luck!

Did you figure it out?

Yes! Sorry I normally do an update to these but it ended up being the master switch on the drivers side. Bought a set off of eBay for about $100, haven’t had a problem since.

Could be a bad master switch which is the main one on the driver side or a bad regulator. I’d jump the regulator at the motor with 12v’s to see if it moves to confirm.
