When you stated that you are getting SOME heat, I feel safe to assume that the amount of heat you are getting prior to your turning up the fan is minimal to begin with, so basically if your getting very little heat to start with then by turning the fan up would do nothing more than dilute that small amount of heat you were getting to begin with at a low fan speed. Bleeding the system and getting all the air that might have gotten into your system was the right thing to do provided it was done properly. So, even with a proper bleeding of the cooling system, the fan control only forces more air out, it sounds that you have a different problem. Was this problem something that was going on prior to changing the thermostat and was that the reason for you to change it thinking this might fix a problem you were having?
