The horn on my 17 F350 is embarrassingly weak. Can hardly hear it in the cabin and sound like a goose with one lung outside the truck. My wife’s Flex is much more pronounced.
Is anyone else’s like this? Is there and upgrade? I don’t want a train or semi horn that’s just ridiculous.
I have one truck doing the same, only one of the two horns is functioning. At times both works and sounds normal. It's not the connection so I believe it must be internal.
I thought the horn was weak until I had the window open one time I blew it. I think the horn is loud, but the cab is quiet. The times I've used the horn, it got attention.
Haha....I thought it was just my truck. My 2017 was really loud when I locked the doors but my 2018 sounds like it is sick lol. To me my 17 was way too loud anyway.
I've seen a few aftermarket air horns like STEBEL that are inexpensive and do a good job. Or you could do like I did and install a Ranch Hand bumper on the truck and let them ogle 300# of solid steel in their rear view mirror. Nothing says "please move" like a nice bumper.
On my 93 F-150, the horn started out ok, but then went "sad" as you described. Still made noise, so I wasn't too concerned. Then after a major collision repair in 95 (got T-boned at an uncontrolled residential intersection), the horn sounded like someone's last gasp. Went back to the Ford dealer that did the body work and a tech came out to look at it. He thought the horn was on the driver's side (as it had been in previous years) which was opposite the T-bone hit, but the horn was in fact on the passenger side. After I blew it for him, he leaned over under the hood, fiddled with something, then said "try it now" - presto, full-blast dual horns. Tech said the wire fell out, no charge.
