My powerfold mirrors are not working at all. The passenger side mirror works when I select a memory position but I can not adjust it with the switch, driver side does not function at all. I can not adjust either mirror with the switch. I have changed the switch and checked the fuse so both are good. My driver seat still functions as I know the fuse operates both. I do not hear the motor running for either mirror when attempting to adjust them. Can anyone give me an idea as to what is wrong? I'm hoping I don't have to replace any motors...any tests that can be run?
