ExtraP

I have been having an intermittent problem with rear passenger window. Sometimes it works fine, other times it only goes up/down in very small increments, or like yesterday, it didn't work at all. Eventually I got the window to roll back up, 1" at a time. Same result whether or not I use the button on the driver's door, or the button on the RP door. When it's not working, there is no click (Relay?) when I press the button. My gut says maybe a pinched wire but I didn't see anything suspicious when I pulled my door panel off. I guess I am asking if anyone has had this issue. Since it's intermittent its tough to test for power because the window has been working both times I had the door panel off. Thanks in advance
