My passenger side high horn isn't working.  I replaced it with a new one and still no luck.  the connections and fuse look good and the low side is working.  any suggestions on what the issue might be?

Not sure what you mean by seat cross-member?  is it possible the relay is bad with one horn still working?

My horns are intermittent, one day works, the next doesn’t.

Had one horn replaced once and it didn’t help.

I’m at 95k miles and thats been my only issue. I’ve learned to live with it.

Did you test both horns when you did the replacement? The should always work when you apply 12 VDC to them.

Did you check the wiring to the horns?

Any steering wheel noises? Has the steering wheel been off before?

A Porsche mechanic checked them when they reinstalled one of them. It worked for about two days.

It must be the wiring, I will check that myself. Thank you very much!

The steering wheel has not been off to my knowledge. I bought the car with 30k on it.

When I hit my lock button the horn sounds perfectly, not sure if that’s within the same system or not.

The alarm/locking horn is a different horn.

 

The front horns are cheap horns (on all Porsches)  - which is why I suggest testing them off the car with 12 VDC.

I replaced mine with electric air horns.

Thanks, I sort of assumed it was a different horn.

I will take you advice and change them out. I don’t like the sound of the factory horn anyway.

Thanks again for your help!
