Thank you for that information. You could go about diagnosing this a few different ways. You could check the signal from the horn in the steering wheel right after the clockspring to ensure it is good or you could go right to the relay and check the inputs.

Customer: replied 9 months ago.
which is easier
Expert:  Amedee replied 9 months ago.

They both are about the same. However, I would check the signal from the horn switch after the clockspring first because if it turns out it is missing a signal to the relay, then you will need to check this anyway.

So you will need to gain access to the wires leaving the clockspring or column and find the gray wire to see if it is getting ground when pressing the horn switch/pad

am guessing getting beyond my ability. will have to take back to shop. thanks anyway
Expert:  Amedee replied 9 months ago.

It is actually pretty easy to check this. All you need is a voltmeter. I can send you a wiring diagram of this circuit.
