Does anyone have a diagram showing which relay does what.
Or can anyone tell me which one controls the A/C fan.

Do you mean the ones in the fuse box? The ones that are fully diagramed if you type "Fuse Box" into the Wiki?

In this case, the aircon has two relays; K1 Normal, which makes the fan run as soon as the engine starts, and K6 High, which boosts the fan speed when needed (I think this is triggered when you actually turn the air con on).

Yes the ones in the fuse box, thanks for that.
