I have a 1995 Ford F-150 Pickup. My horn does not work…horns are ok, relay is ok, fuse is ok, horn button is ok. The only thing I can find wrong is voltage going to relay from the horn button is low (around 9 volts). The panic button that makes the horn beep works. I don’t know if they’re related somehow, but a week earlier the cruise control shorted out and blew a fuse. It knocked out the anti-lock brakes and steering wheel lockout. Seeing that the horn and cruise control both have their wires going through the clock work wiring to get to the steering wheel controls, could this have shorted out the computer to affect the horn? Maybe the horn went then and I did not know it.

Thanks for any help you may be able to give me.

 

"The panic button that makes the horn beep works."

Whats a panic button?
I do not think my 95 has one.
