I’m just doing some maintennance work on the car as I prep for winter. I thought I’d take another look at this problem. Do you have any kind of diagram that I can reference for the horn?
in my googling, I can find these part numbers, but no diagram or video showing the location of these items:
- Horn unit: 4F0951221a
- Horn wiring harness: 4F0971073
- Horn Relay 7.1: 4H0951253C
[UPDATE] Nevermind. I actually took the time to poke at the horn unit through the grill, and discovered (as I suspected) that the shop mechanic who replaced the front-end on the last job, did not lock the electrical connectors to the horn unit. They were just sitting there and I had to use a couple long screwdrivers to force them both into place.
