2005 X5 e53 4.4i facelift air con problem

[talljames]

Hi Guys,

My air cool air stopped working the other week. Took it to a local mechanic and he re-gased it but found the clutch wasn’t engaging. Suggested a new compressor but he was able to gas it ok. Have been reading a ton of material on fourums and many mention the aux fan between the radiator and the bumper. I don’t have one there. The only fan I have is between the radiator and the engine. I can see three wires coming from it (two heavy and one light) which tells me that perhaps this is it? But, I thought the engine needed a fan for cooling.

Anyway, the forums say that when I start the engine and turn on the air-con by pressing the snow flake button that this fan should start up for a short while. Mine doesn’t start at all. Is it supposed to on my model?

Any help would be appreciated.

regards
