i have problems with the heater in my e60 525d!!
i recently changed the thermostat on the car beacause it didn't heat properly and i thought that was the problem!
so , i changed the thermostat and it worked a little better at first!! the air was hotter but the fan speed don't go up in speed!! from the 3 level remains the same!!
if i press the windshield defrost button the fan goes to maximum speed!!
Tonight besides the fan problem , also the air didn't got hot!!
i also noticed that if i press the max button for summer ac it doesn't start!!

According to your fan speed, it might be the final stage resistor
