In Reply to: Does our BMW Run faster when Heater is fully on? posted by Chad on December 08, 1999 at 23:29:50:
This is my understanding... Running the heater will help cool a hot engine, it doesn't increase or decrease load. When you run the defroster, the compressor runs and places a load on the engine, the compressor also runs when the AC is on.
: Just wondering.... Any reliable sources??
: Thank you in advance.
