Steering Column Airbag Clockspring Repair Ford Superduty 1999 Up

Check your fuses first, then a vacuum leek second. To reset the air bag light unplug the battery for 30 seconds then reconnect. If the light comes back on take it to a garage as the air bag can be very dangerous.

This vehicle has a part called a "clockspring" that is located in the steering column beneath the steering wheel. It is the contact unit for the steering wheel controls and the air bag wiring in the steering column. Sounds like to me that you have a bad "clockspring" and it needs to be replaced. The part is available aftermarket from many parts stores so you don't necessarily have to go back to the dealer for the part. The part is not extremely hard to replace, however, it may not be suitable for a DIYer (requires steering wheel puller). You may want to take it to a trusted repair facility and have them repair it for you. The labor is approximately 1.5 hrs at the given shop rate. Good luck. Hope this helped.

this problem is typically fixed by replacing the air bag clock spring, located below the air bag itself. Chrysler offered a lifetime warranty extension for certain 1996-1998 minivans with this problem. contact a Chrysler dealer and give them your vehicle identification number to see if yours falls under this warranty.

your car instore the obd2 trouble code, check out it. You can use the us703.

The computer controls the horn and looks for a signal from the Remote Keyless Entry system or the horn button. Due to the fact that the horn works with the RKE but not when you press the horn button, would cause me to suspect that the Clock Spring mechanism, which is also used to activate the Driver's Air Bag, might be malfunctioning. When the Clock Spring breaks, the computer does not get a signal from the horn button so it can not opperate the horn. If I remember correctly, when the Clock Spring goes out, the Air Bag light on the dash either does not light up for 2 seconds when you first start the vehicle, or it comes on and stays on all the time, which is to let you know that the Air Bag is not functioning, and the primary cause is the Clock Spring. So check your owners manual to see if the Air Bag warning light on the dash is functioning normally. Your local Chrysler dealer can quickly and easily check the function of the Clock Spring, Horn, and Air Bag system, through the use of the DRB scan tool. If it is in fact the Clock Spring that is malfunctioning, the Air Bag module and the steering wheel must be removed in order to replace the Clock Spring, which should be left to a trained professional, that has been educated on the proper handling of the Air Bag system. You wouldn't want to accidentally deploy the Air Bag, as you could be injured. That and Air Bag modules can be expensive to replace.

blown fuse the air bag light needs to be reset by dissconecting the 12volt side of the batt. for 2-min then recconected

If the air bag light is on, the horn does not sound when the pad is depressed (but does souns when you activate the alarm) and the cruise control doesn't work (but the lamp lights up when you first turn the key on), your issue is probably with the clockspring. This is a device that keeps an electrical connection between the steering wheel and the rest of the car regardless of steering wheel position.

Replace your steering column clock spring which carries the signal from the air bag, horn switch, and criuse controls.

check your fuses and connections if thats not it you have a short somewhere
