Finally sat down and documented the Passendger Air Bag Deactivation Switch repair. Who needs a 60 buck switch from Ford when it can be fixed for a $1.27.

 

That's a great fix isnt it. I did mine awhile back.

 

Holy cow this worked great. thanks for saving me alot of money! it is really simple to do also.

 

Wendell, Welcome to .
Stick around and be better informed.

Click on the links at bottom of my Sig and enjoy.

 

I love this forum. Every time there is a problem with my truck, I find the fix on here and it usually costs less than $20.


Is the idea here to replace the bulb or just to reflow the solder joints? It seems like the bulb should be replaced. If it is to be replaced, can I get a yellow one at radio shack?

 

Yes the idea is to replace the bulb. I used a clear bulb when I did mine.

 

Hi today i replaced my led for the airbag. The local electronics store sold me a led and a diode they said i needed being its a 12 volt system.The light stoped flashing but the led does not light up? Where did u get your led from? The led is in correctly. Thanks if you can help .

 

I used the small bulb from The Source, which used to be Radio Shack. It was number 1121 or 1127 I think

 

You don't need a diode in a DC system, but you do need a resistor to limit the power to the LED. Are you 100% positive that its in the right way?

 

I USED A 12V LED FROM THE SHAXK, AND ITS BEEN WORKING PERFECT....sorry about the caps.

 

Thats the best bet there. Its got the resistor built in.

 

Thanks for all the information. I got my led from radio shack this time and it worked great,red in color now that is all they had in 12 volt.I needed to pull the radio out also to get at the switch.Thanks again. 99 f350 superduty xcab 8ft bed drw 7.3 a/t 4x4 116k

 

I got the 2-7 flashes, I took mine apart, soldered in the new 12V red LED, then decided to check my old bulb. It worked fine when given 12v. Now that I look in the small swich box, I don't see a physical attachment between the little circuit board and the white round piece that turns with the key. I don't see how the white thing touches the circuit board.Maybe somethings missing, but what or where I don't know. I may just need to buy the whole switch?

 

Ok, maybe I see a spot on the other arm of the white thing that touches the board. But I put it back in with the new bulb and it still flashes 2-7, and won't light the bulb in either position, even after discoing the battery. One other note, I just bought the truck, and someone had a little splice coming off the fuse for the air bag. It wasn't currently looked to anything, but the fuse was blown. I replaced the fuse, but still nothing. Talk about a dumb fuse to tie into.

 

Anyone know how to test the circuit or switch to see what's not working?
