I have a 87 GT. I blew my Horn/ Cigarette Lighter fuse a few days ago. So i checked out the horns, turns out one of my horns were bad. So i dis connected the horns and drove like that for a few days. ( During that time the horns were not connected i used my cigarette lighter for my radar detector. ) Today i went and bought a dual horn, mounted them and hooked them up everything worked, looked promising. Drove to the local murrys to get some carb cleaner for the weed wacker, when i got back in the car i plugged my radar detector in and i saw a spark from the outlet to the plug. Blown fuse again... No horn once again... Got home ( really ticked off because ive went through like 10 20 amp fuses ) I put another 20 amp in and tryed the horn, it worked, pluged in my radar... there went the fuse. I decided to try one last thing. I disconnected the new horns and put another 20 amp fuse in, i was getting ready to plug in my radar when i saw the fuse blow. The horn was disconnected... and nothing was in the cigarette lighter.... Whats the deal? Anyone have any clue whats going on here?
Blown Fuse.....Blown Fuse.... Then... a blown fuse..

You should be able to disconnect one of your horns at a time to find which is bad. I have heard the change in the lighter problem before so don't feel to bad. The lighter doesn't even work in my GT or my 4 banger, but both have working horns.mustangjoe87 said:mine does the same thing but i dont have any change sitting in my cigarette lighter. every time i press the horn button it blows a fuse. a month or so before this i was at work and the horn just started to go off by itself. is it posible that my horns are meesed up or is it a short
