Question about BMW Cars & Trucks
BMW 330d 2002. My demister and heating do not work
Check the heater valves in the engine compartment. This is a solenoid valve that allows the hot coolant to circulate through the heater core. Hope you have not used radiator stop leak or anything like that since that can plug the heater core sometimes

I had the same problem with my 325 coupe. I had no blowing air and the only heat i got was coming from the engine. I got an auto electrician to look at this and he found it was the heater motor resistor that was broke. I got mine from BMW and cost me about £120.00. I hope you can get it sorted.

in the fuse/relay box. is my guess.
on some cars its an option, needs fuse, relay and grid, and harness upgrade. the FSM Covers this fully, why not get one.
