I have a 02 f250 and my power mirror switch on the driver door panel is acting up. It will move both mirrors up, down and left. For some reason it will not move either mirror to the right. Should I replace the switch or is there another solution for this problem? If I need to replace the switch is there any secret screws or groments hidden for me to be aware of? The local Ford dealership has a new one for $29.95 is that to high or is there a web site I could purchase one? Thanks Bart
