Will a 2009 mirror work on a 2014? All options are the same (power glass, power telescopic, power fold, heat, signals). The wiring harness looks the same and it has the same # of wires. Part numbers are different.

 

Im assuming you are referring to tow mirrors, ive always heard 08-16 uses ths same mirror, but the one has a bigger blind spot mirror.

 

Quick answer, if it's the driver side mirror YES. If it's the passenger side mirror NO. Folks, let's not forget the passenger side mirror on all 2011 to 2016 model years incorporates the ambient temperature sensor. Replacement of this mirror with a passenger side mirror intended for use on a 2008 to 2010 model year Super Duty will result in a "Check Engine" light on with three ambient temperature sensor related DTCs to go along with the symptoms of operating a vehicle with the ambient temperature sensor input absent.

I have already seen more than my share of these on my doorstep the dealer, a few of which have resulted in sales of the correct mirror.
