Air conditioning fault

[Michmash/eddie]

Good evening gents,

Well I have just bought my 2005 Passat b6 1.9 tdi and foolishly didn't check the air con before handing over my cash. I have the basic air con with the dials, no fancy climatronic etc.

When I turn off the "econ" button I cannot notice and change in the revs, the air does not get cold at all (even at motorway speeds). I have looked at the compressor clutch and it seems to be spinning and constantly engaged regardless of wether the econ button is on or off. The small fan does not start either.

I am praying that the air con pump is not broken as I replaced this on my Bora this summer and it was not cheap.

I'm looking for advice, common faults, anything really.

Cheers all
