Disco 2 Td5 Airco pump mystery??

[tulipandthistle]

Hi all,
I let the garage refill my airco system but now when I switch the airco off it is screeching but when the airco is on it is fine???

Any ideas?

when aircon is switched on the compressor clutch is locked, when off it should release,it sounds like the clutch

Cheers JM is that fixable or is it just replace with a new pump? Does that mean the gas has to come out again?

worth pulling clutch apart in situ first

Cheers James, where can I order a service kit for the airco? Don't seem to be able to find it?

i dont think its available as a lr part, its possible perhaps to get a used clutch or depending on issue get a relacement bearing or contact denso supplier
