It could be any number of things unfortunately. Some possibilities are ... computer, switchs, vacuum lines .. etc., etc. Your best bet is to take it to your mechanic. We had a clock spring replaced at no cost by a dealer. Our air bag light stayed lit, and both the horn/cruise control didn't work.

The vehicles affected are the Dodge Caravan and Grand Caravan, Plymouth Voyager and Grand Voyager and Chrysler Town and Country from the 1998-2000 model years. Four people have been injured in crashes because of the defect, according to records submitted to the National Highway Traffic Safety Administration. There also have been 782 complaints about the defect to Chrysler and NHTSA. The defect involves a clock spring that supplies current to the driver's side air bag, the horn and the cruise control. If the clock spring is working properly, the air bag warning light will illuminate for a few seconds when the vehicle is started. If the air bag warning light isn't working properly, the clock spring may have failed. In a release Friday, Chrysler said it would begin notifying customers about the recall this week. Dealers will replace the clock spring for free on vehicles with less than 70,000 miles. The company will extend the warranty on the clock spring for vehicles with more than 70,000 miles. Chrysler recalled 1996-1998 model year minivans in 2002 because of the same defect, NHTSA said.
