failure rate of horn relay?

Post by minimike »

My horn was not working. I dropped the panel under the glove box and with the key on, jiggled the wires on the relay with the horn button pressed. I did get the horn to sound, but when I put the relay panel back, no horn.
Anyone had a similar experience? Do the relays get 'soft' inside and need replacing? Can I open the relay up and resolder anything?

My relays are the 38 year old originals so I don't know of any problems with them. Could you be moving a wire that's broken inside the insulator when you're reinstalling the panel? is this an air horn?

not air horns, but dual electric horns. I'll have another look at the relay and wiring. Maybe I can jump it and see
if it's the relay.

Is your steering wheel turned any? or off center any? I know in my car, with the wheel slightly turned the horn fails to sound sometimes. But then I also know when making hard turns (sometimes parallel parking on a steep hill) my horn will sound without being presses. ---its amazing how useful that feature is sometimes, like when you have to swerve out of an idiot drivers way, or when when your parking to pick someone up.

Lex,
Obviously your horn problem is at the button and wiring in the wheel. Mine is, I believe at the relay or wiring at the relay.

Sorry Mike forgot to add, it only started doing that after I dropped the relay panel under the glove box. I'm sure my problem is systemic to the wiring at the wheel but dropping it 'might' have started that problem.
