The heater fan ONLY blows the air, it does not make the temperature of that air. Your heater temperature controls how hot the air is. Adjust your heater temperature for hotter or cooler air.
very common problem it seems, there is a relay, under the bonnet,centrally located,just under the windowscreen. controls the heat. this is commonly at fault, and simple to change
heater vent will not readjust to any position

The heater blend door is vacuum actuated. You have a vacuum leak somewhere.
