So you just got a 108 and now you wonder what severely twisted maniac designed these heater controls and how on earth do you get heat out of this thing? First: pray. If the blower fan does not work it's sometims cheaper to buy another 108 with a working blower motor than to fix this as the car is seemingly built around the blower motor; this is not a joke. Take heart, there is an article that while aesthetically may not be the best does enable you to get heat. Look here. In the meantime here are the pages from the owners manual you probably didn't get that explains how the heat works.
