How do you install turn signal lens on side mirrors on a 2005 F250?

If the signal flashes on the outside of the glass, then the yellow lens will pop off the mirror assembly using a small screwdriver etc for bulb access. If the signal flashes inside the mirror assembly, the mirror will need replacement or there is a wiring issue

Check to see if there is a hidden screw on top or on the other side. If there is none, try to move the lens side a little bit before pulling it outwards, a tab on the back must be holding it.

is this a plow truck? Either way i would start with the switch. Try doing simple continuity tests on the switch. if power doesnt flow when the switch is pushed in a direction, then replace the switch. If its not that i would try jumping wires on the mirror it self to test it. You have to know which wire is ground coming from the mirror.

these are readily available on ebay-i.e.:

the built in turn signals in mirrors them selves? they are not replaceable have to replace whole glass

- Adjust the mirror so the mirror glass is in as far as it will go (meaning if you were looking in the mirror you would see the side of the truck)

- Look inside the mirror housing
- Locate silver clip
- Using a flat screw driver, push the clip in
- Lenses will pop out on the outside
- Remove bulb
- Replace bulb
- Snap back together when new bulb in place.

The door panel must be removed to get to the wiring. On a 04 250 you need to: pop off the moulding covering the mirror mounting nuts. Pry the window switch plate forward then up to disconnect it, then unplug it . Rmove the screw behind the switch plate and behind the reflector. Push up on the door panel to remove it.

i need repair fuse on f250 diesel

Actually the first answer was right.  On my 2007 Sprinter chassis, the side mirrors have an upper flat mirror and a lower convex mirror.  The upper mirror comes off exactly as described; by tilting it so that it faces down, and then gently lifting it from the top to slide it off the track. (On my sprinter the mirrors are heated, so there are wires that remain attached when you slide it off. This reveals three screws that you can get at with a torex screw driver without needing any flexible shafts etc.  It appears that there is a fourth screw or clip of some sort on the bottom, but I was not able to figure out how to get the bottom convex mirror off to get at it.  That would enable the removal of the full shell. Even without that bottom screw I was able to flex the shell enough to get the turn signal lens assembly out.  But removing it entirely requires reaching in with needle nosed pliers and rotating the bulb assembly a quarter turn, and then reversing the whole assembly to get it back.  In my case I was replacing the turn signal lens, but it should work the same for replacing the bulb. Good luck.

First, after receiving an email from FixYa about my "Ford 1992 Ranger Problem" which was not my query at all, as the question was titled "F150 and F250 Mirror Compatibility" , I am asked for money for the answer. Then they ask me what the solution is, so they can sell it to some one else. Why would I pay someone when they can't even get the question right.
Incidentally, the solution was to ask someone competent.
