02 grand prix gt----well here we go again lol my horn for some reason blows all by its self. im just driving down the road and it blows for 3 or 4 secs then stops.also when i turn on the blower fan the dash goes black sometimes.any one had these problems or have any ideas of what it could be.im very close to just trading this car in.
 


mine did this too, but i never looked into it and just pulled the fuse under the hood and was done with it.
 
I have the same problem in my 02 gt. It will blow just randomly. Also my dads car had this problem but every time you would turn there steering wheel it would go off. There was short inside the steering column that could be whats wrong too
 


Christ I've had this same thing happen.. Now mine doesn't work at all.... The fuse is good and you can hear the relay click when you press the horn button

i bet your horn is dead... if you un plug it and run a pos and neg wire to it from the battery it should sound off. if not its dead.

not sure where the horn in in GP i have a regal, but its in the bumper some where, mine is under the battery iirc.

Nope, not dead, wasn't grounded properly... Shined the bracket up and a small spot behind the bracket on the frame and works fine now..... I'm still battling this headlight issue though LOL... Prolly a BCM getting ready to fail
