What is a clock spring in the steering system used for and what happens when they go bad.

I dont know why we have it or what it does but read in another thread that it clicks when the wheel is turned.

Good Luck,

I'm no expert, but I believe it's called that because it looks like a clock spring when it winds and unwinds. Basically, it's how they make a positive electrical connection to the airbag and still be able to turn the wheel back and forth. Sometimes they run the cruise control and horn connections through it as well, so if those are dead too and your airbag light is on, you have a pretty good idea of what is wrong. I don't know if this applies to the WK though.

A general idea of what a clock spring assembly looks like behind your steering wheel:

A clock spring is basically an electrical connection that enables your horn, airbag and other steering wheel mounted electrical controls to function while the wheel turns. When it goes bad you have no functional airbag, horn and etc. They are'nt badly priced either, you can pick one up for 100 to 200 bucks if they go bad. They are'nt something you want to try to replace yourself either without eperience and knowledge of airbag systems and auto electrical, a mistake can be deadly!

they are replaceable by the shade tree mechanic, but do not attempt it with out the guidance of a factory shop manual. and please if you try it, remember to physically REMOVE the battery from the car, and to not touch the air bag wiring for at LEAST 10 minutes to prevent accidental deployment of the airbag. once removed, just be careful with the bag, and use common sense while handling it, keeping in mind that it is a mild explosive device. these same guidelines also apply to servicing the reel side of the front seat belts as well.
