I have a 2014 F-250. The power mirrors work and adjust the glass using the switch, both sides. The folding and telescoping only works on drivers side, passenger side won't fold or telescope. Also, the marker light on passenger side is not working. I don't hear a motor "trying" to work at all. Checked fuse #8 and #32 seem fine.

 

(Heck to see If the roof Marker lights are working. They are on a different fuse

 

if you checked the fuses and confirmed wiring is good then its pretty common for the motors to die. The inside of the mirrors get wet and the motors rust and die.

And no, Ford wont sell you the motors.

Go on https://www.gruvenparts.com/shop-by-car/ford and look at 1st item. You can buy replacement motors and upgraded metal gears to restore the power folding towing mirrors.

 

its a 10 amp fuse btw
