One of the two horns is failing on my 2000 E320. I found the one in front of the grill but can't find the other. Of course the other is the one that is failing.

Can anyone tell me where it is located ? I saw a post about another model having the second horn under the headlight but I didn't find it there.

 

Never mind. I finally found it under the headlight. Actually under the frame which is under the headlight. The foglamp access panel under the bumber gains limited access. Couldn't get to the bolt for the old horn so I found a suggestion elsewhere on the net to just mount the new one right next to the old one. That worked fine. Just posting this reply in case anyone come here seeking the same information.
