Default uncontrollable horn

Can anyone tell me how to disable my alarm system without disableling the horn. My horn will go off anytime, anywhere. Sometimes it will be weeks between going off and sometimes hrs. There is no apparent reason for setting it off. It may go off at three in the morning setting in the garage. Have had this problem for yrs. and have just kept horn unplugged. Car is torn down for the winter and would sure like to fix it now. I've tried pulling the fuse in the center control panel, but that also disables the horn. Any ideas from you experts? '88 L-98 coupe 4+3.

There are 2 black wires going to terminal 1 of the horn relay. One of them is from alarm and one from horn switch. Figure out which one is from horn and cut the other.

I had the same issue. It was solved by replacing the horn contact wire inside the horn button on the steering wheel. Take the horn button off and remove the contact wire the next time it goes off. A cheap fix if it is it.

Good Luck

If it goes off at 3 in the morning I'm surprised your neighbors haven't disconnected it already.

Have you got any ideas on how to figure out which is which ? I have located the two black wires you are talking about, but can barely get to them. Greatly appreciate your help.

Remove one and try the horn button. If the horn works, you have removed the right one. If it doesn't, then it's the other.
