Horn not sounding on 2012 sprinter. Hear an audible click in the cab when depressing horn pad on steerkng wheel. Also, looked under the hood and it is not easily located. Any help to troubleshoot and repair is appreciated.

If you hear the click it has been my experience that the horn is bad. Horn is located on passenger side under the grill. If you remove the 4-5 screws that are on top of the grill you can then remove the grill and the horn should be easily accessible. Part no. should be A9065400076.

update. took the grill off, pretty simple and found the horn in great shape. tested it for connection current to the horn and found in order. hit the horn a couple times with a wrench and some dust / dirt fell out of the bell opening. Wella, works great now. Funny, must have been a combination of lack of use and crud in the housing. Thanks for the info, saved my $50 bucks.
