Replacing dying horn
#1
#2
as for the parts I would call around at a few of your local junkyards to see if they got what you need, depending on the availability of those cars someone should have what you need, as for where the horn is located most are inside the bottom of your radiator support or under the edge of your bumper, my 90 740 has 2 horns

before replacing the old horn, you might just make sure you're getting a full 12V at the horn terminals.
they are behind the front grill, which should be pretty easy to remove (open hood, a few plastic 1/4 turn pins come out, and the grill just lifts off....). disconnect both horns (there's a usually pair, they are a high-low note pair), and have someone push the honker buttons on the wheel while you read the voltage at the terminals.

those are guaranteed to wake the dead.

ohhhh, my bad, it was our 240 where they were behind the grill in front of hte radiator. and my friend's benz. and some other cars. hah.
I still think he should check the voltage first before getting new ones, it might just be a crummy ground or bad power connection or something.
do note, in a 740, you don't hear how loud those horns are from inside. stand in front of the car and have a friend honk them for you.

somewhere in between the 240 and a mack truck or maybe a big Benz S class. very authoritative no-nonsense HONK with the two tones.
actually, I don't have those horns on anything right now. I hardly never use my horns. In most impending emergencies, by the time you could honk, its usually too late, so I generally practice avoidance.
A couple friends of mine have them on their bmw motorcycles, when they honk, everyone is looking around for the freight train, and instead its a couple codgers on their 35 year old touring bikes...

oh yeah, about 20 years ago, a friend of mine had a euro model 450SEL with that, I think it was a late 70s model. It switched from the standard 2-tone horn which was similar to that supertone to a 'Freeway Blaster' which is a rather directional and EXTREMELY loud horn that sounded like a freight train. ah, these, Fiamm Freeway Blaster Horn :: Aerostich/RiderWearHouse Motorcycle Jackets, Suits, Clothing, & Gear (a highlow pair), so in total, that benz had 4 horns.
one thing the motorcycle folks figured out, those vibrating plate type horns HAVE to be mounted on a really solid surface. if they are just sorta hanging there or mounted on something flimsy, it seems to absorb half the sound. Me, I just have the stock horn on my bmw tourer, it goes MEEEEP MEEEP loudly enough, I hardly NEVER use it, I'm always riding like I'm completely invisible and assume the cagers can't see me.

I just changed the horn on my 91 940. I like the idea of the horn reflecting the car. Im not sure quite what horn sound mine shoudl reflect tho, haha. I got a air horn from online for about 45 bucks shipped. Way cheaper than the dual OEM which was about 40 for one, requiring 2. The mounting of it was alittle off, needed to do some custom work and wiring, but got it fitted in under the driver front bumper and its definately a noticable air horn, nothing crazy like a Truckers horn, but much louder than stock, gives you that effect that people wonder how a volvo just made that sound.. I like it.

If you look at the body of the horn, there is a small screw. Before you replace the horn, get somebody to push the horn and turn that screw. It is an adjustment for the contacts of the horn that get worn with age. Adjusting them can sometimes bring back the horn to what is should sound.
