Before you take it in you may want to remove the door panel and check the wiring connections. When I first bought my celi the passenger side window would sometimes work and sometimes it wouldn't. I thought it might be the motor or the regulator. Fortunately I decided to change my speakers out before I took it in. While I had the door panels off I noticed that a wire clamp had come loose behind the door panel. It suddenly dawned on me that this may be why my window was having problems. I reconnected the wires and tested my window and I haven't had any problems with it since. It doesn't take long to take the door panel off and it isn't hard. You'd be surpised how many times something that seems like a big problem is caused by something small. Eliminate the small things first before you pay someone to reclamp some wires .
