Hi, guys. This is my opening thread, and I hope to learn a lot from you guys.

I have a problem with my passenger side power window. In short, the right side power window is dead. I cannot roll it up or down with the right side power window switch, nor does the master power window switch roll it up or down. However, an amateur mechanic I know working at a used car lot told me that in his opinion the master power window switch needs to be replaced. He finds that there is nothing wrong with the window motor, as he easily rolled the window up and down using an external power source. The fault, he thinks, is in the master switch, because he thinks that the passenger power switch is merely an extension of the master power window switch.

So far, I shopped on eBay motors and bought three switches cheaply, since I did not see the point of paying $200-400 for a new master switch. So far, all three switches failed to open or close the front passenger window, and one rolled the right rear window down, but not back up.

I wonder if the fault is something other than the master switch?

Does anyone here have an idea of what I should do here. There is a new master power window switch for $200 that I might want to grab, but I want a second opinion before I pull the trigger.

 

Post a pic of the motor. My telescope steering wasn't working, but I opened it and cleaned it out, regreased it and "viola". I'm sure it's the same idea. I'd take it out and do the same. A pic would help though. Look and do a search here "telescope steering wheel", someone posted a pic of the motor.

 

It seems that the master switch is ok. Each door has a little black computer in it responsible for operating the window (among other things). If the motor works when hooked up directly to power, then the door computer is not giving power to the motor for some reason. At this point, I might consider replacing the passenger door computer if I were you.

 

Is there a Part # for this door computer?
