Heater not strong enough
I bought my 323is used, when it got to winter the blower motor was phenomenal. now here it is approaching the colder months again, and it does not seem to be hot enough and blowing that strong. the radiator is full, all connections are good, it works on all speeds so I know its not the resistor block. even the AC doesn't blow that strong. only on the 2 highest settings does the motor make noise,.
