Horn works had to stand on it yesterday because some idiot pulled out in front of me in a ford focus.I just had my cruise worked on.Does you're horn work?There is what is called a clock spring in the steering wheel that runs the cruise.The horn is tied into this.useally if the horn doesnt work neither does the cruise.I just had this replaced on my 96.
Not completely correct.. The cruise will still work with the 3rd light out....But if you use the turn signals it will click off. It does this because the voltage is wacky when the 3rd light is out and it unlocks the torque converter when you use the turn signal or when you tap the brakes like it's supposed to.... This is why it can also heat up a transmission... Imagine your torque converter constantly locking and unlocking with the turn signal....Obviously this applies to autos only...It is also true that the third brake light on the cab has to be working, if it is burned out, the cruise dies since the cruise control senses the third brake light current to shut off the cruise control.
