Thanks Neil. Something I'd come across in search before > http://www.honestjohn.co.uk/forum/post/ ... tm?t=63198
, seems to be something common with the Mondeo. Ford sell a shim kit which I've ordered the shim kit from my local dealers this morning, worth a go tomorrow...
Suppose if the compressor cycles on and off in use (as I believe it does) then it's quite possible this could be the cause. Going to try and get the refrigirant checked whilst I'm at it.
Just read that thread - good news that there is a shim kit, and access is reasonably easy to sort this.
In a lot of cases, garages would simply say you need a new compressor - they don't tend to do much at all (if anything) directly with air-con. The regas things, these days, tend to be all automated - hook it up to the ports, tell it the make and model, then leave it do it's thing.
As to compressors, I've seen them operate in two manners - engagement of the compressor, via the clutch, dependent on several sensors and factors, low gas causing the compressor to cycle every 5 or 10 seconds - this is the scenario, where the compressor is cycling more frequently than it should, that probably results in notable wear to the clutch plate.
On other systems / compressors, so long as there's some minimum gas pressure, the compressor will engage, and pretty much stay engaged permanently, until you turn of A/C, but gas pressure appears to affect the vent temperature / cooling, and presumably other aspects of how the compressor is operating.
If it's blowing cold, now, when the compressor will engage, then it's reasonable sign that there's a decent amount of gas in the system. When it does work, what's the sort of time between the clicks of the compressor cycling?
