My rear passenger window just stopped working - it made a grinding noise when it went down, and then would only come up about an inch. I could hear the mechanism work briefly, and was able to get the window partially up by pulling up on the glass while holding down the switch. Then it stopped completely...nothing from either the switch on the driver's door or the rear door...does anyone have an idea as to what has failed? I'd love to know before I take it to the shop...thanks!
