Also check the connector. Check for an open-circuit.
HINT: The fault may have been caused by an open-circuit in the supply to the relay.
HINT: The voltage must be 12 V at both terminals #1 and #2 for relay 2/17.
HINT: In particular, check that fuse 9 in the integrated relay/fusebox in the engine compartment is intact.
Try a new horn relay (2/17).
