A supercharger increases the intake by compressing air above atmospheric pressure, without creating a vacuum. This forces more air into the engine, providing a boost. With the additional air in the boost, more fuel can be added to the charge, and the power of the engine is increased. Supercharging an engine adds an average of 46% more horsepower and 31% more torque.
the resistor for the blower motor is busted blower works on high with out it
Check your servos.
Bad blower resistor?
The wiring, switch or blower has failed.
when a blower motor only works on high, it is usually due to faulty resistor board. Should be located in the duct near the blower. the purpose of this is so the air blown by the blower keeps the resistors cool.
The blower may simply have burned out. If the blower is out then the heater probably still works.
The blower motor works on only one speed. The blower motor resitor pack is defective and needs to be replaced. It is located on the blower housing in the engine compartment just below the blower motor.
