I have a 2003 BMW 325i, and the heat is not working. Anyone know how to fix this

What is your question?

I replaced these parts: Thermostat Blower motor Water pump I also bled my cooling system multiple times. My coolant is topped off and the car does not overheat. I used to only get heat when the car was moving decently fast with high rpms, but now I get no heat at all. My car only blows cold air. Help please.

How long has your 2003 BMW 325i had this problem?

A couple of weeks
