D3 Horns Don't Work

[Pippin]

Any ideas? Glove Box fuse is OK and you can hear clicking from there when you press the horn on the steering wheel.

Put a multimeter in the connector at the horn.
Have someone press the button.
No reading, no circuit.

Likely they have a belly full of water.

Nick - remember there are 2 horns - a low tone and a high tone.

One is visible behind the grille which fills up with water when driving in the rain and stops working first, and then a second one is hidden out of sight near the expansion tank - not as usual for this one to stop working as it is better protected from the rain.

Easy to unplug and test with a direct 12v supply - but be warned they are loud when removed (when working).

Ours had the horn button on the wheel get stuck while my wife was getting out of the car one day. She bumped the button with her handbag and had no idea what happened. Apparently it didn't take long at all for the problem to "solve itself".

It wasn't until I went to use the horn and found out both had burned out we figured out what had happened.

No water and there is power on the horn cable but no continuity on the potted printed circuit board on the back of one horn (Relay?) that distributes power to the two horns. Horns themselves have continuity. New horns I guess.
Thanks for your help Tombie.
