Left Rear Window inop, anyone have schematic??

2018 TRD Off-Road, 4 door

RR window inop from driver switch. From passenger rear switch, only goes up.

Swapped switches with LR and RR door. The RR switch works, as the LR window will go up and down.

The RR window motor works, I pulled it and plugged it into the LH connector and it works both ways.

Test light jumped between the terminals on the plug for the RR window motor, I have power to go up, but power for down. When using the RR switch.

With the test might jumped on the RR window motor connector, I have no power up or down.. FROM the driver door switch. I’m leaning towards a bad master switch.
But would like to know if anyone has schematic for window circuits.
Is there anything between the driver master switch and the passenger rear window.

Thanks !!!

from look of it, no module between the Master switch and RR window.

 

Have you tried resetting it? I had to do this when I replaced the battery in my Lexus and the auto windows wwouldn't work... Ill look up the process ..

 

This is for the rear passenger door, it doesn’t have auto function feature

 

Had the same happen to my RR switch window went down but wouldn’t go up. After searching TW I ended up just taking the switch out and cleaning the contacts. Put it back in and has been working fine since.

 

Gotcha… I swapped the rear switches and it works in the left door. So that tells me the switch is good.

 

Did the right side still not work with the left side switch in it?

 

Correct

both rear switches work, with the driver rear window. They do not work on passenger side rear window

 

With mine I thought it was odd that it was the rear switch because it wouldn’t work from the master switch either. Wonder if yours is just the opposite? Try taking the RR switch out of the master and cleaning the contacts. Worth a try

 

BOOM!! Found the issue

so going off the schematic, I had power on both circuits coming out of driver window switch … so next was OHM testing. Probe on red wire , from Master to RR switch, .04ohms. Did the same on the black wire, OPEN circuit.

Moved the pass though around, on the right rear door, got continuity !! Broken wire inside the pass through !

Thank you for the schematic!!

 

Now it's how or why so it doesn't happen again.
