Horn

[barrettfb]

Hey all,

My horn isn't working in my 1985 300D Turbo.

Any suggestions as to first troubleshooting tips?

Thanks!

Disconnect the two wires, and apply 12 volts across the horn to see if it makes noise.

Have a friend push the horn button while you measure voltage at the wires. If no voltage, check the fuse, then check the wiring. Bad ground would be likely suspect.
