I've upgraded my stock tow mirrors on my 2015 3500 to power folding boost auto mirror with switch backs. I've also had to add the upgraded factory mirror switch to allow me to add the folding function. Question is has anyone had an issue with one of the mirrors not folding? Currently my drivers side works great. When I plug my passenger side in it will not work. If I plug it into the drivers side plug it will work just fine. Could this be a misplace pin in the connector? Any help would be great.
