Greeting all... I have issue for my 05 TL 6MT left rear window just stopped working. Can't get it to move from any switch. Driver switch when presses/pulled makes click sound at the rear windows switch. I have opened rear door and swapped window switch from right side(that works) and no change. I have tested the fuses and P/W relay under the dash and all good. I have replaced window motor/actuator assembly and no change. Now new issue. Today I pulled the P/W relay, tested it, and inserted it into it's location in the relay panel under the dash. now none of the rear windows work. before I removed relay I could activate the right rear window. now not even a clicking sound in the rear switches. I recheck the fuses and both good. rechecked relay and it clicks with 9v batt across the coil. ... one weird thing. with the roof interior lights front/back...they stay on much longer than before and something had drained my battery over few days as I left the right rear door open while working on issue. no lights were on and car was not touched for two days.. i recharged car battery but ceiling lights take long to auto turn off after doors are all closed. Car has 186kmiles and still driving strong otherwise. also I have electrical and service manuals from Acura.. allowed me to check more but at a loss.. I haven't gone through testing each connector from master windows switch.

1) need to get right rear window working again.
2) need to get left rear window working again.

any help is greatly appreciated.

 

update: I was able to get right rear window working again. all I did was reseat all fuses under the dash.

remaining issue is the left rear window motor does not work. no noise nothing.
the left rear window switch clicks when activating from driver switch or from right rear window switch.
I checked continuity of two wires from motor to switch and wire is good.

suggestions please?

 

Now check continuity from master switch to left rear motor. my guess is there is a break in the wire harness going back there

 

update:

thank you for your suggestion.

The voltage with key turned to ON position the YEL/RED wire from the rear switch should have 12v. I found around 0v so there is issue with this wire going forward to fuse24. I then followed the wire to the pilar(two connectors C751 area). I measured both ends of each connector and there is 12v. from back of the connector belonging to rear door wire loom. So there should be break somewhere from the rubber boot going to the door switch. next steps go through wire loom of rear door starting in the boot section.. and replace/fix wire.

 

Sounds like a solid plan to me! best of luck on that search, it's not fun but very rewarding once completed.

 

found the broken ylw/red wire a few inches from pilar connector! I removed the entire wire loom from door and s soon as I pulled the boot towards the other end I saw the broken wire. see image:
