In my 2005 Civic LX sedan, the passenger's side rear window will go down, but not up. My first thought was that it was the switch itself, so I swapped the switch from my driver's side rear door to the passenger side, but no change.

Has anybody else run into this? Is it possible that the motor will only work one way?

There are more threads where people have the same problem, but this is a start. His problem was the wire, itself.

 

My dad and I did a bit of testing today with a test light, and whenever he supplied the ground to whichever wire, the window would operate normally.

 

I just bought my 2005 civic like a month ago. I work at honda so when i bought it i told them i wanted as it no service. when i bought it the passenger rear window didnt go down, so i told honda service where i work and replaced the window actuator...now works fine. getting my paasenger front done friday. Oh yea i bought the extended warranty on it make sure you have warranty or else a bit pricey. those seem to go bad though
