I will say it, this is crap advice from all, you must go through basic diag before deciding what the fault is.

You must check for volts at the horn and work back.

Diving in with 'its the CIM' is going down the road that bad mechanics do..........plus the CIM failure impacts more than just the horn (as its a connection inside that has the issue, hence why metal clips were fitted.....)

And Dave...........an earth on a car, really 

Don't be so NEGATIVE 

I did say.....

Check the basics first ...

PLUS...
Terry can't check anything because the car is not with him, it's going to a garage i think, and garages are not always honest 
warning him of the possible CIM fail ,so he knows it's an expensive job IF the garage have to replace/reprogram it .will at least prompt him to take a jar of vaseline   


I hope for Terry's sake it is a simple fault

Agreed, understood, always my plan. Trouble is the car is in Enfield, 120 miles away. She put the car into a garage to cure the engine light on, they changed the thermostat, making a coolant leak, changed the thermostat holder to cure that, charged her £330, and returned the car with no horn. On my instruction she complained to the garage about the horn, and this morning the car is back with them to sort it, checking 12 volts and decent earth.
Shall I find 12 volts positive at the horn or at the horn press?

If it's at the garage, you're unlikely to find anything...

Horn circuits tend to be grounded at their mountings

Catherine rang Greenfrog garage, was told car needs new horn, new Vx horn will cost £74, none in UK, 7 days from Germany. I told daughter to collect the car, bring car home at Christmas, I will look at it.

You can buy a pair(high and low tone) of decent quality branded horns for less than £20.

My apologies to Greenfrog garage, it was Chase Side Motors who changed the thermostat on Catherine's car and created a coolant leak, then changed the thermostat holder, then left the battery lead loose, and now want to change the horns

something like THIS £8.50 would save more painful bills from a garage ,easy for even a novice to fit with minimal tools

I have a pair of Omega horns on a mounting. I imagine they would serve on the Astra if that were the fault. Car will arrive home on December 23rd.

[dave the builder]

you may have to cobble a bracket together out of the astra and Omega ones, but that won't be hard 
or just fit one
pay yourself double time when you do the job , it being Christmas   
good luck with the fix
