Hi all! My front passenger window does not go up or down. Without testing the old one I replaced the motor and regulator. Still nothing. I have checked all fuses, relays, tried different switches including trying a different drivers master switch. I'm stumped. It doesn't have auto up and down. 2002 Acura TL type S. All other windows work. Any where else I should be looking? Thank you. Oh yes I tested the new regulator and motor. Both are fine.

 

Back a long while ago, the windows would stop working randomly for a day, then stopped working altogether.

I found out that the "Power Window controller" and all motors were working good, and I eventually traced it to be an intermittent +12V power supply wire going to the window controller box. The +12V supply wire was not supplying +12V consistently. So I cut the supply wire, and patch a new wire from the fuse box to the controller. Everything works good every since.

So check all the signal and power/Gnd wires too.

 

So I have power to the switch. The two wires that leave the switch and go down to the motor I don't understand how that works. I think it's a ground gets connected when you use the passenger window switch. So I'm stumped again. Don't know where any grounds are located to test. Ugh

 

Your 2G TL-S can't be that much different than the 2G CL-S.
The G581 ground for the right side harness is shown below.
Look under the front passenger seat as shown below.

 

I appreciate the info. Big time!

 

The 2 signal wires that go to the window motor will reverse polarity depending on up or down operation. It is +12V on one wire and 0V on the other to crank up the window, and is in reversed to crank down the window. Check to make sure that these voltages are correct during operation.
