Do you have a air bag light lit on the instrument cluster ? I ask this because , if the air bag light is lit , could be a clock spring problem . I know ,what the heck is this guy talking about . You have a air bag on the steering wheel ,the horn button is on the steering wheel . The clock spring is located under the steering wheel , in the top of the steering coulmn . It has flat wire tape in side that allows the steering wheel to be turned full left to full right , keeping the horn , air bag , an any other button's on the steering wheel connected electricly to the vehicle. Plus there is a relay , when you push the horn button it energizes the relay turning on the horns. Watch these videos , will explain a little better .

The horn, cruse control and air bag each get power from the clock spring and each have a wire plugged no to it. The horn wire is probably not connected. When the clock spring breaks the horn and cruse control stop working and the air bag light stays on.

The horn gets power from the clock spring. when the clock spring breaks you loose the horn , cruse control and the air bag light stays on indicating it is disabled. {The clock spring is under the air bag in the steering wheel }

get the manual to do the proper installation .

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.

2003 corolla, horn stop working and now air bag light is on. Was told a senor was out on the steering.

There is something called a clock spring in the column that is used for the airbag, horn and cruise control buttons. This clock spring if messed with will cause a/bag light to come on and possibly cause a/bag failure if there is a collision. DON"T mess with the wiring in the column. Run new wires in to the horn or install an a/market horn.
