Fan will not blow on high. Replaced the resistor but it did not solve the problem. what next?
This is a great car but the Air is not blowing hard. What comes out is cold but the speed does not change on the blower. It will blow through every port, dash/defrost/floor but only on lower speed. Replaced the resistor as it looked as though it had been hot but it did not cure the problem.

There is a linear control mechanism for the blower motor that controls fan speed.
You may also have a problem with the air vent mode control if it is blowing out all of the vents at once.
I am providning you with wiring diagrams of the entire A/C/Heater circuit.
