Passenger window and mirror failure

[Digi]

So this is odd. My main switch drivers side works for every window but the passenger front window. It can unlock the door, but it cannot put the window down or move the mirror. I checked the passenger front door, it also can't move the window down, but it also won't unlock doors. Thought it might be switch, but that doesn't make sense for both master switch and passenger to not work. Checked fuses, everything looks good, last option I can think of is the motor. However, I don't think that handles the power mirror for the window.

Anyone experienced this? Does the motor for power window have something to do with the mirror or is it possible two different issues?

Thanks.

Welcome to the forum! Please give us the details of your truck. Kind of hard to help when we don't know what you're asking about. Without knowing anything about it, and just going by past experience with other vehicles, I would take a look at the driver side switch. Since it's normally part of an assembly, you often can't replace just one switch in the assembly. If it's a new truck and still under warranty, I'd probably take it in and have it fixed.

ah, sorry. 1500 09 slt.

Really? I guess I was thinking it was the motor or passenger switch since the passenger switch won't open the window either. Is their a connection between the main switch going and the passenger? Could it **** the connection in a way that neither would work?

That's been my experience with a lot of different cars. But it depends on how the circuit is designed. Often the driver side switch for the passenger window and the passenger side switch are in the same circuit. So if one of them is bad neither switch will seem to work. Since you also have an issue with the mirror switch I'd suspect the driver side switch.

Cool, thanks, guess I was so focused on it being a passenger side issue I didn't even think it could be the drivers side. Appreciate the reply, have to see if I can find one to swap out.

I'd probably see if there is a way to test the switches before buying a new switch assembly. Looks like a new switch assembly is $125 plus shipping from BAM.

Same thing happened today to my truck, no mirror lights also

Update: I still haven't found the issue, replaced main switch, passenger switch, checked fuses. Let it go for a while as I had other things to deal with but now wondering if it's the motor. That seems odd though as the mirror won't work and I don't think that's tied to the window motor.

 

[mikeru]

The motor is easy enough to test. Unplug it from the harness and apply 12 volts to the power terminals. The motor should turn one direction. Reverse the connections and the motor should turn the opposite direction.

As far as the mirror goes, unless you can nail down a common point of failure I'd just troubleshoot one issue at a time.

Thanks, much appreciated

I guess I’d look for a lost ground on the passenger side.

Have you checked the wires for power with a volt meter. Since you can't move the mirror or window, it sounds as if there could be a power supply problem. Could be a broken wire. Also, and not sure here, but it is possible one power wire feeds the three items (window, lock, mirror) and the the switches just complete the circuit. Check a wiring diagram. Maybe the power feed split is bad such as a broken wire where it passes from inner wall into door.

Thanks, add that to my list of things to check.

I haven't yet, it's odd as the main switch will lock the doors, but no window or mirror for passenger side. Even tried replacing both passenger and driver side switches, nothing. My guess was a fuse, but that seemed a long shot, thinking now a wire somewhere is loose or connection bad.

Chrysler/fiat or whatever they call themselves these days are notorious for loose and corroded grounds. Causes a lot of weird crazy problems.

 

[Digi]

so more fun and an update, I have replaced main driver side switch, passenger switch, motor for window as well, none of them fixed the issue. thankfully I was able to return everything that didn't work, my last option is electrical which I just haven't gotten into yet as I know it'll probably be a pain. You would think as far as we've come with computers in cars we'd simply be able to hook up a reader and it says hey, it's electrical, the hunt and search method was easier without all the computers, now they seem to be more of a pain, then again I also miss real keys to use in my truck.

Did you ever figure it out ?

 

[04fxdwgi]

Have you checked the connections on the door module? Windows, locks and mirrors / controls go thru it.

 

[04fxdwgi]

Probably should start another thread on this for your problem, as this one stopped be active July of last year.

 

[Digi]

Never did figure it out, tried a variety of items and no solutions. Ended up getting. different truck, that one got totaled by a lovely hit and run guy while crossing a bridge. Sorry for not updating.
