2003 Ford Explorer 4 door. Front right window won't roll up, just down with switch. What could cause this if the motor is good?
The contacts inside the window switch may be faulty.
Remove the window switch and check for voltage at the wires for the up side on the window switch when you press the up button. If you don't have voltage then replace the switch.
If you need more assistance then get back to me, we can diagnosis the problem further if needed.
