I bought my 2005 f150 but it didnt come with a owners manuel so can someone help me out and tell me which fuse (or relay if it has one) I should look to be possibly replacing to get my horn working again. Thanks in advance

 

If you did not get an owners manual with your truck ( purchased used ), you can download one from Ford :
