Hi,

I have a 1993 honda accord station wagon and recently the driver's window intermittently stopped going up. I suspected that it was the switch, so I cleaned the assembly and got most of the black gunk out of it. This failed to help the problem, so I took the window motor assembly out and that relieved the stress of the window, however it only worked intermittently. From there I tested the voltage coming from the connector to the window (red-blue and red-yellow). When the window switch is pushed down it is -11.24 volts, however when pushed up it it can be within the range of 1-2 volts.

I am out of ideas of what is going wrong, unless the drivers power window control box is broken. Please advise what I should do next. Thanks!

 

A high resistance is sapping the voltage transmitted to the motor. Switch seems likely culprit despite cleaning. Did you disasemble switches and clean contacts?

Suggest trying to swap a switch from another position to driver's position to see if that fixes problem.

good luck

 

I fixed the problem. After 20 years, there was more gunk in the thing than i had expected. I re cleaned the contacts that the window works great now. Thanks for your help.
