Have relay and fuse and horn still not working
I have the same fault in my 313CDI.
By pushing the alarm button the horn works.
Sometimes the horn worked intermittently so I suspect the wiring/ contacts on the steering wheel?

hi
Check whether power is coming to horn.
if ok means then check the horn
thank you
SOURCE: horn stopped working, fuse and relay is good
With test light check voltage at horn assembly on both wire's, could only have one, horn assembly itself could be ground, have some one press horn button while checking, if there is voltage replace horn assembly, if no voltage horn pad at streeing wheel bad. that's being fuse and replay are good.

Change the brushes in the heater motor.
Common fault on Merc Vitos and sprinters.
Brushes are on ebay. Search for "heater brushes"
