I was rudely awakened last night, the horn on my Lesabre went off all by itself, (the car had been off for 6 hours). I had to disconnect the - terminal on the battery to get it to stop. Has anyone had this happen to them? Question # 2 where can I get an electrical schematic?
I've isolated the problem to the combination air bag / horn pad in the steering wheel. I disconnected the battery and removed the air bag module. the dealer parts people say that the only parts available are the wire leads to the module. Has anyone successfully repaired the horn switch that is Incorporated into the air bag?
did you ever fix your horn problem? I drive a 94 Park Ave Ultra and have the same problem. I'll honk my horn and it stays on until I give it a good hit or two. Sometimes even the slightest grazing will set it off as well.
