Chrysler Repair: Cirrus/Stratus horn blows all the time, flexible coupling, clock spring


Question
i bought a horn relay part to  install. when i put it in the horn keeps going off like the alarm is goin off and it won't shut off by itself. could there be a problem with the wiring? is this a usual occurence? is the problem a do it yourself job or should i just take it to a local mechanic? oh i have a 95 cirrus

Answer
Hi Tiyonna,
When the horn activates as you describe, it probably means that either one of the two horn switches on the steering wheel is inadvertantly activated (try press/release on each, several times to see if that clears it), or the flexible coupling between the steering column and the steering wheel (called the clockspring) is shorted to a nearby metal surface. If flexing the horn switches doesn't fix it, then try rotating the steering wheel from limit to limit and see if the horn stops blowing at any point in the rotation. If not, then about the only was to get to the bottom of the issue is to remove the steering wheel and check the clock spring and the switch wire to see which is grounding out falsely. That grounding out is what causes the relay to fire off the horn. Let me know if you want to do this yourself and I'll xerox and postal mail you the pages from the manual that describe how to do that.
There is another possibility if neither proves to be the cause and that would be that the body control module which can also blow the horn is grounding this same wire by error. But that is not very likely and would be noticed if after you unplug the clockspring the horn still blows.
