New member here with a weird problem?

[summer]

Hello everyone. This issue is concerning my mother's 1997 Aurora. She bought the vehicle in 1999 when it had just under 30,000 miles on it. it currently has just under 60,000 miles on it. 
The other day we were in her house and the horn started to blow intermittently by itself. It blew appx. 6-8 times before stopping itself. The doors had been locked via the remote at the time. Nobody was near the vehicle went the horn sounded. Gremlins maybe? Possessed horn? What with the low mileage, was the vehicle saying drive me? Please help us.

Hello did the sound continue like you press on horn and never let go or it sound it more like alarm goes in any out?

My guess: bad theft deterrent module.

Well, these cars do like to be driven! 

I knew someone with a similar issue on a Grand Am...turned out to be the horn pad in the steering wheel. In that case it was a continuous sound (not like an alarm) that would just randomly start and stop when it was parked.

Had a similar issue on a Chrysler Concorde I used to own, except that did it while I was driving. Oh that upset some ppl! Turned out to be the airbag/horn clockspring in that case.

It blew intermittently by itself. 6-8 times total and that was it. 

Lets say the problem is a bad theft deterrent module, could it simply be unplugged to find out? Also, this occurred only once, so I don't know how long I would have to leave it unplugged to find out. Could it be unplugged forever and she simply have no alarm?

I am not sure how 1G works but if you unplug the module the car might not start. What I would do if it happened again press the panic (red) button on the remote and see if it stops if it will than something with that module if it wont than something else.

I want to thank everyone for their suggestions. So far, the horn has not "gone off" again.

After reading all the ideas here, we thought of another one. What if we simply disconnected the horn fuse while it is at home? Would it cancel the alarm? If that's not a good idea, we also like the one of not using the alarm and locking the doors the "old school way."

Please continue to give us your thoughts and thank you in advance.

Hello even if you close doors old fashion way it still turns the alarm on after 10 min. so if someone will try to get in to the car without the key the alarm will go off

Make sure the door jam wiring is all together. Pry the boot and check for split wires.
