Hi- my 03 Accord's front passenger window is stuck in the upright (closed) position. When Ipush the power window door buttonor master power windowdoor button, I hear a click in the door panel area, but the window will not move at all? Does nayone know if my pw motor or regulator has gone bad- how can I troubleshoot? I'm willing to open the door panel and take a look, but would appreciate some pointers if possible. No sense in opening things up without a plan. Has anyone experienced this type of failure?

Thanks all!
