Replacing the Signal Switch on a Ford Bronco

My signal switch had developed some play in it resulting in my wipers not responding with out a wiggle of the lever and I lost the front signal lights and the signal in my mirrors.

Start by removing the tilt wheel lever, it unscrews.


Next removing the cover, there are 4 phillips type screws to remove, 3 of which are access on the bottom

The forth one is locked on the back right, you can see the screw hole better in this picture.



You'll need to remove the ignition tumbler, while pushing on the release bearing turn the key to the run position, this will release the tumbler and it will slide right out.






Slide the top cover up and over the gear selector.


Now remove the 2 torx screws that hold the switch in place and disconnect the 2 wire harness on the back of it.




New Switch on the left, and the old one on the right.


Now test your lights and wipers.


Install in reverse and your done.

It's worth mentioning that, before replacing the MFS, you should test it.



Another worthwhile point is that MANY vehicles use a similar switch with a cosmetically different lever. Even the Nissan Quest (aka Mercury Villager) uses an electrically-identical MFS, but some of the luxury cars (like the Crown Vic/MGM/LTC) have a slightly different switch for the cornering lamps. So if you're junkyarding, there are plenty to choose from, or if you're buying new, there are several options.

Ok I figured I'd post in here just so I didn't make a new thread. I bought a 1997 F-350 and the column is the same. I got it torn apart because my key was jammed. It either got stuck in and would start the truck fine OR it wouldn't go in... I got a new cylinder and thought that would fix it but referring to picture number 5.... the turquoise piece behind the cylinder holds in a metal piece which is broken on mine and then behind that is a little gear. Next is what I think is causing the problem... The plastic gear that runs above the other gear seems to be stuck and won't allow the key to turn back all the way into the off position and defiantly won't let it turn into the acc position.

How can I get this to work, and on top of that... How can I get these parts? I have the cylinder and can find the switch, but I need these other parts I think. Is one called the tumbler? Any help would be great!

Um no, the newer rig have a combo switch which has high beam, turn siganal and wipers all on one switch.

The 78 had a three seperate switches.

Thanks for the write up. That switch went bad in my sons 94 Grand Marquis and my daughters 94 F150 last night. Both within an hour of each other. Whoever did the search to revive this thread thankyou to you also. Made finding it much easier.
