Alright so this driver side rear window has been non functional since I purchased the Jeep 2 years ago.
Already bypassed the window lock switch hardwired, not the paper clip method haha


I stabbed a multimeter through the power window wires behind the door panel
(not connected to regulator) and got this:

Without touching either switch with meter in DC reads constant- 0.476 V

Using driver window switch
Down: No change from constant voltage
Up: 0.017V

Using driver rear window switch on door itself
Down: 12V
Up: 0.55V



So yes the window will go down, but will not come back up using the switches in the Jeep.
(It will come back up using a battery and manually applying/switching power)
Which confirms the regulator works.
I looked over all the wiring from the door up to the driver switches and didnt see any cuts or shorts?
Kind of confused here, I am not new to wiring by any means but I have no idea where to start to tear into this issue?

Any help would be greatly appreciated

 

hmm, well youve done your part it testing the issue, so thank you! i gotta say you sound like you know more than me on the subject, so ill ask a question or two- despite having bypassed the switch, is the wiring for all the door switches thru the master switch on drivers door? and if so, could a bad switch still be the cause of it not working? what voltages do the other doors read? would low signal from other doors indicate the master switch in any way?

 

I am pretty sure all windows go back to that master switch yea. Just not sure how all windows could be working besides the one.


Im thinking it could be, and I would take off the other door panels if I had to, but I am very lazy and rather wouldnt haha

I tried using the switch from the other rear door once before and it didnt change anything. I am seriously considering trying to figure out how to just wire up a constant 12V to both switches and be done with it. Would probably be the easy route

 

wiring the 12v is a good idea.. i hear ya on the motivation factor.. once im into a project its all good, its just the getting started..

 

Now I get to locate a wiring diagram for a 13 year old car how fun.. haha

But Ya! What I tend to do is take apart whats broken so then I am forced to fix it

 

theres lots on google and on here.. wont be hard to find one.
