could some one please tell me how to remove heater fan that is located behind the glovebox, as i need to replace it, as it is making a noise as though the bearrings have gone when it is on low speed, it is ok when on full power..

It comes out of the housing from below - need remove the trim in the top of the footwell, and the glovebox itself to get at it. I think it's held in with about three screws, and just one multiplug to power it.

Standing on your head in the passenger footwell is the best way(laying across the front seats), as it really helps to be able to see what you're doing.
