I am looking to buy a '96 "M" Xantia 1.9TD estate with the basic A/C (at least I assume it is with a button on the dash with a snowflake symbol on) and the car is great in every way except.... the blower fan only seems to work in certain settings ie its either on or not, no graduation also its extreemly noisy, sounds like a Cessna at take off. There is also no air coming out of any vents at all. Can anyone tell me what could be the prob and worse case scenario especially as it does have the basic A/C system! Cheers Rob
