1991 240sx Horn Problem...
So I have a 1991 240sx and for whatever reason the horn would never work. So I looked at the fuse box and low and behold there was no fuse for the horn. So I replace the fuse for the horn and now the horn works, but the horn stays on and you cant get it off unless you take the fuse out. So what is making the horn stay on, is there a horn relay I can replace or what? Thanks!!!
Life begins at 6000 RPMS.. You will notice an audible change in engine noise, large increase in acceleration and any female passengers will immidiately start to remove their clothing.
this a easy 1 trace the wires an find out.
bad ground
neg. bad ground would make it not work at all. there is a hot wire from the car crossed with the signal wire for the horn keeping it on all the time.Originally Posted by spinks
Bad grounds can work either way. They can make your headlights come on when you brakes hit, depending on the nature of it. You're probably right though hot wire didn't even cross my mind. I seen some hilarious ground problems.
