    Where the heck is the horn relay on this model? I've checked under the hood (fuse is ok), and under the left side (drivers) kick panel and can't find it. Amazingly YouTube has not been helpful either.

    Thanks in advance,

    I have a 1988 single cab and the factory service manual which should be the same as 1987. The FSM shows there is no relay for the horn.

    Horn doesn’t work. Checked the horn itself and it works. Thought checking the relay would be quicker than taking the steering column apart to check the connection. Guess I’m pulling the steering wheel and column apart.

    Start with just the horn button. Could just be corrosion on the contacts themselves

    Its probably the contact spring that's worn out and its not rubbing with the other contact on the steering wheel. I believe they are brass and get worn out due to that fact that its rubbing or should be rubbing in order to work. pulling the steering wheel off you should see if in fact its that. hope this helps
