Hard to believe that running the fan motor faster would improve the heater
effectiveness. It would just blow more lukewarm air, IMO. At speed the fan
isn't contributing much, anyway. What you really need to do is raise the
temperature of the heat source. Your options there include running a higher
temp thermostat, blocking off (part of) the radiator and/or oil cooler, and
improvng the flow through the heater valve, either by adjusting the cable
(to ensure it opens all the way), or performing the operation discussed here
recently (rebuilding the heater valve to increase flow).
