Heater problems

[Durene]

I couldn't find another thread for heater issues.
I have a 2005 320i and it takes longer than it should to heat up....however, that's not my main issue. If the car is cold like around 0 degrees or lower my heater fan doesn't come on until the car have warmed up a bit and sometimes I can hear the blower squeal for a few seconds. Any help would be appiciated before I take it to the mechanic.......it often has a musty smell when the heater first comes on.

Thanks so much

It sounds like possibly two issues. If the engine is slow to warm up and tends to run cold your thermostat could be stuck open (better than closed). If the heater/AC fan is squealing from a cold start, it could be that the fan shaft is slipping within the barrel/impeller assembly of the fan. I am not farmiliar with the setup of your model, but have a look at the assembly on RealOEM.com Online BMW Parts Catalog. It might give you some ideas about what is happening.
Good luck
