I've got a 1998 Ford F150 that runs perfectly, except the passenger window wont roll down. All the other power options including the driver's side window work. I took the door panel off and made sure that all the wiring harnesses were connected properly and tightly, and it makes a faint clicking noise when your press for the window to go down, but no movement at all. Any suggestions? And there's insulation underneath the door panel and I dont think it will go back on if I take it off, so I haven't tested the window's motor. I'm hoping it wont come to that. Thanks in advance for any help. -Spencer
