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.
