Pull the fuse.
There are sever possibilities to the horn not blowing consistently. The horn relay or horn button are the most common followed by a loose wiring connection or a defective horn.
My wrx 1995 stopped working because of the carbon brush on the rear of the wheel. fitted after market neon horn swith to dash to get round it.
You can replace the horn button on your 1992 Pontiac Bonneville by removing the center steering will cover. Remove the horn button retaining screws. Remove the horn button wiring harness. Reverse the process to install your new horn button.
It's in the fuse box under the dash. Look at the cover of the fuse box and it should tell you which fuse is brake lights and horn. On my Legacy it is the middle row, third one in, fuse 12 I think.
where is the horn for a 1997 kia?
Where is Horn for 1997 Pontiac Transport?
I am not sure if ut will be the same, but in my 1995 subaru impreza the horn relay was located under the dash, behind the fuse box. You have to look for a small connector with three wires going into it. The wires should be red, blue with a black stripe, and red with a green stripe. It is hard to get to, but why would they want to make it easy to fix your own car?! Hope that this helps someone, it took me a entire day to find it!
To wire up a car horn with a button you first need to run one of the wires from the horn to the battery. Take 1of the wires from the horn and run it to where you want the button to go. Connect the wire to the button and that's it.
peel the horn button's vinyl cover off first. then unscrew the horn button off. peel the horn button's vinyl cover off first. then unscrew the horn button off.
Could be the relay or switch at steering wheel Check to see if there is 12volts coming from the fuse. If there is power (12volts)on both sides of the fuse, then it might possibly be the horn switch. Is there 12volts at the horn when the horn button is pushed?
Push the car horn button....
