My partner's 1985 Honda CRX has been without a functional horn since she bought it a couple years ago (i know, not a good idea, anyways...) This weekend, it started honking involuntarily and continuously to the point where she had to disconnect the battery to stop it. After looking at it, it appears someone had tampered with it-probably trying to steal something, maybe the whole car-they had pryed the horn housing/plate on the steering wheel up a noticeable amount and in doing so woke the dead horn. We did a cursory inspection of our options to remedy this issue and realized we can't connect the battery or the horn will blare and can't remove the fuse because that kills our brake lights. Advice?
If you are able to replace the horn assembly, even one obtained from a salvage yard this may remedy. A missing horn fuse breaks the circuit causing your brake lights and certain models dome lights to become inoperative.
