Question about 1998 Mercedes-Benz M-Class
I was told there are two horns.I replaced theWhere are the horns located to test them?
About four things to do, first check voltage at horn with key on and button pressed. If voltage there try moving the small gap screw back and fourth a few times. If that doen't work replace horn. If no voltage check fuse and horn relay, you should be able to hear the relay click when you push the horn button, If not and fuse is ok. Switch relay out with another on on the car. If that doesn't fix it check the horn button for continuity.

If the test lamp illuminates, refer to the Horn Test.
Ignition OFF, disconnect the inline harness connector C275. Ignition ON, test for B+ between the horn relay control circuit terminal B and ground.
If less than B+, test the control circuit for an open/high resistance. If the circuit tests normal, replace the underhood fuse block.
Momentarily connect a 3-A fused jumper wire between the control circuit terminal B and ground. The horns should work.
If the horns do not work, replace the underhood fuse block.
If all circuits test normal, test or replace the horn switch
The PCB relay horn system consists of the following components:
