Why would a new blower motor not run on high speed and not get as hot as it used to?

Depending on the make and model it could be the switch or on some cars the circuitry includes additional components like a small circuit board. answer most likey to be the fan switch, a blower motor does not alter the temperature only blows more air to be heated thru heater

I would suspect the blower motor speed resister is shot.

If you only have high speed I would blame the blower speed resister. If you have no speeds and the fuse is good, I would blame the blower motor or the switch.

If the one speed it works on is high speed, it is the blower motor speed resisitor that is bad.

The blower motor speed resistor is burned out. The high speed function bypasses the resistor. The speed resistor is generally located near to the blower motor.
