Due to an incompetent mechanic my Hella Supertone horn's grounding wire was ripped and then reconnected very poorly. The first time I noticed this is when I honked my horn, got a *blaaat* noise then nothing. The fuse had blown.

 

I replaced the fuse, got a short tone, and the fuse blew again.

 

No biggie, I'll just go get some new fuses. When I went to put the car in gear, the shift lock would not disengage. I could hear the solenoid clicking but the shifter would not move out of park unless forced.

 

After I made and soldered in a new wiring harness for the horns and replaced the fuse, the shift lock once again disengages properly.

 

Pull the 20A horn fuse and a screwdriver is needed.

 

Does this seem weird to anyone else? Why is the horn and the shift lock tied together like this?

very interesting.......

I would agree that is weird but I have a strange one of those fuse stories too! In August I was driving in Canada and all of the sudden the engine reved up and it was like the transmission just died. I pulled over and noticed that the tachometer was not working and the auto seat belts, idiot lights, and windows did not work anymore. This pointed towards a fuse but I had never heard of a fuse that controlled all of that and looked at a couple but nothing stuck out as bunt out. Well the next day I had it towed to a Dealer in the middle of nowere and they took a half hour to find a fuse out. The Fuse is labeled as meter and is in the interior fuse panel. It seem to get blown by one of the auto window switches being stuck and overheating the fuse. I couldn't believe that one fuse would disable the vehicle so well!!!! Crazy huh!
