Pressing cruise ON + Coast = HORN!!?!?

I was driving to work this morning and went to set my cruise control, so I pressed on and hit cruise instead of set by accident and my horn went off. I thought I might have just hit the horn by accident so I tried it and sure enough if I press cruise ON and Coast my horn goes off.

What gives?

I had something similar happen with my truck before and it turned out water was getting onto the GEM (generic electronic module). I think that's what it stands for. I had my windshield pressure checked for leaks and resealed plus put some silicone in any holes I had in the firewall on the drivers side. The GEM is on the backside of the fusebox under the dash. Hope this helps.

You may want to check the harnesses in the column. You may have a short where the wired rub against the shifter. I've read about a few wierd things happening in there (first for the CC activated horn though).

Try putting the left turn signal on flashing the lights poping the hood while hittting the brake petal all at once and see if that solves the problem

Sounds like an issue with the clock-spring in the wheel. You will most likely have to replace it, or take it apart. They do tend to have issues, although that is a new one that I hadn't heard of........until now.

Here are the manuals on it: Clock-Spring R&R Manuals

My horn would go off at random times. Driving, parked, truck off, etc.

Rose-

Similar kind of issue to what I had. Sort of. My horn would go off by itself. Really. When I wasn't even in the truck. I pulled the relay to temporarily solve the problem. This also killed my cruise. So they are on the same relay circuit. Even though the problem is slightly different, I think the solution may be similar.

I've printed the big old doc from the link here at work so at least I have some instruction when I tear into it.

Anyone have a link to a photo-documentary of taking out the air bag and steering wheel assy's?

HAHA
while it isnt normal to have the horn go off at random times by itself, on my mustang if you push the on and off of the cruise control the horn beeps. It actually does it on all 4 of my 94-98 era mustangs. Weird i know, but until it starts beeping by itself I wouldnt worry. (94-98 mustangs have hard buttons so the on/off rocker has to fall off before you can push them at the same time)

Yeah I dont think I'm going to worry about this one until my truck develops a mind (and alarm) of its own and starts beeping in the middle of the night.
