Horn wont work but works with the panic button
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.
