I've got a 2002 Espace III. The fan (or fans) no longer blow at all. I don't know how many fans there are though. I've been told that it is probably the resistor pack that has failed. Also, the fan might have caused the resistor pack to fail so it might be worth checking the fan and replacing if it doesn't look too good.

The air con still works though only blows through when the car is moving so it is just about possible to de-mist the windscreen.

I've searched for instructions on how to replace these parts but haven't found anything at all that helps me. Could anyone point me in the right direction? Many thanks.
