Does the horn have to be a certain loudness or is it enough that it makes a sound?
Reason: my Volvo's got two honkers but it sounds like there's a duck sitting on the bumper when I push the button.
Alternatively, can they be repaired? They have a rusty old Philips screw in the front - is it worth a fiddle or am I going to the breakers before the MOT on Monday?

Some of them can be 'tuned' by adjusting a screw.

unless it is very quiet then it will pass, often a dead horn can be revived, get an assistant to press the horn button and thump the dead horn sharply with something metal, if it makes a squeak keep hitting it till it sounds continually, then if necessary adjust the points with the screw.

It's one of those tricky parts that's 'in the opinion of the tester' - my 155 got a fail for 'horn too quiet' at one testing station, but it was retested elsewhere, and passed.
Thanks chaps.
I'll give it a good thump/tweak with an appropriate tool later and see what happens.

The message from "Mungo \"two sheds\" Toadfoot" contains these words:
If you tweak it, remember to lock the screw again afterwards, either with the locknut or a dab of sealant. They happily twiddle themselves if left unlocked.
my Volvo did that - i disconnected one and the other sounded louder and a solid/long blast. Maybe i was lucky in disconnecting the duff one first time, 440 g reg Volvo
As it happens I took my ancient 740 for MOT yesterday ( passed, yipee ), now I seldom use my horn so was surprised by the puny little squawk, however the tester made no comment about it.
That's interesting. Perhaps it's a common problem like the dodgy fuel gauges, sagging headlinings etc.?

Yep - all my 740s had this. The horns are low down right in the line of fire from spray etc. Never bothered my MOT guy though.

That sounds more like a Maestro!
Heh.
I fixed my headlining with some spare self-tapping screws and black plastic washers left over from building one of the two sheds. Worked a treat and gives the rear of the headlining an interesting medieval look.

And leaves the roof looking like a hedgehog?

Aha! I eschewed the inch an' arf eights for little tiny screws wot only go into the fibreboard stuff. I'm not silly, you know :)
Si
oooooOOOOOooooo! I *likes* the sound of that. Is a portcullis a viable swap for the radiator grille, would you say?

We were somewhere around Barstow, on the edge of the desert, when the drugs began to take hold. I remember "SimonJ" saying something like:
Won't be any roof-sitters, though.
