I ordered towing mirrors off amazon last year. Got them in and installed them, I hook them up and tested both sides before putting everything back together. Both worked, Installed them, Passenger side still worked, but driver side didn't. Emailed company they sent out another set, error happened and I got 1 correct and 1 for a 2010+ sized mirror. Emailed them they sent out another set and they were correct. months go by and I didn't have the need to change the mirrors out as i already had them adjusted to where i needed them(folded down) I did some trading with a friend and traded him the mirrors that were messed up for a leveling kit and some cash. We took old ones off and up new ones on my truck. Tested before installing them everything worked great. Start the truck and turn it around in the driveway. My driver side works fine now but my passenger side on goes left and up folded in or flopped out. Im not a wiring guy and I need help figuring out why it has done this.
