Cruse control steering wheel buttons light wiring

SOURCE: 1998 Ford windstar horn wiring

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.

It could be carbon deposits on valve seats keeping valves from totally closing. You can try getting you a can of motorcraft PM3 top end engine cleaner and get engine up to operating temp then remove one of the small vacuum lines from the intake and draw the contents of the can slowly into the engine.After you have drawn in the contents shut engine off and let it soak for about 45 minutes then crank it back up and let it run until it clears. Now it will smoke like a forrest fire while you are doing this so don't be alarmed,just tell the neighbors you are spraying for mosqitos.This may cure the problem. If not you may be looking at a valve job.
This can be verified with a compression test if this is what is causing it.

it could be the front axle u-joint binding up. i had the same problem, and that's what it was. i put greaseable u-joints on both sides.

This one hits home. They usually start honking the horn randomly as well. There are a ton of covers to remove under dash then you follow the steering shaft to 3 sets of bolts that bolt the shaft in to wings off the sides. Once you remove these bolts the steering column will pretty much fall on your head. Watch out for that. It hurts. There's going to be a few plugs to unplug from the harness and remove the small string that connects the shift indicator, watch out this one breaks easy. I would suggest disconnecting the negative battery cable before you start this process because you may shock yourself or accidently explode the airbag. Hope this helps, be careful and good luck! Oh by the way, let me know how this turns out for you. I'll be checking in from time to time.
