WARNING: WORKING WITH AIRBAGS CAN BE LETHAL!! USE EXTREME CAUTION!!

Now, if you are still willing to do this, please follow along.



Disconnect the Battery, positive (+) and negative (-) sides.
Locate your fuse panel, (usually under the drivers side dash) and remove the fuse for the air bag (Inf. Res.).
Now, keep your head to one side, (common sense, just in case) if you reach around the back of your steering wheel, you will find two hex bolts on each side. Remove them.
Please be careful, with those bolts removed your bag will pull easily from the center of the steering wheel, there is a wire there, (I have seen it yellow, and I have seen it green) you need to cut that wire, make sure you leave it long enough so you can reattach it if you want to later.
Put the airbag someplace safe, FACE UP. (Unless you want a hole through the ceiling if something happens).

thanks stevieb42 i have done that and found the ribbon cable inside the rotary swtch had snapped off from both ends so the airbag wouldnt have worked any way i think ? so i need a AMR4726 type switch now
