Re: 02 406 hdi
It is more than likely a faulty heater control module (£50 odd quid at dealers), you can see the module wiring if you look to your right from the heater fan or follow the red wire to where the red wire terminates.
Check if you have live at the right side red wire with engine on, if so then the module is probably at fault.The module is held in by one screw and is about 3inches long when pulled straight downward.
A search on the forum will reveal lots of info on this subject, including problems with the ignition switch and burnt wires in the motor housing/connector.
