Do you have a hi speed blower motor?
Do you have a hi speed blower motor?
I have no hi speed blower motor. I have replaced the fan switch, the blower relay,and still have ni High speed, on a/c or vent or anything. Anyone else had this problem?
What are the resistors on a blower motor?
Blower resistors are made of several resistors with different resistances. There are also two additional circuits used for the off state of operation as well as the highest speed of operation. In the off state, the blower motor is effectively disconnected from the power supply.
How is the speed of the blower motor controlled?
The blower resistor is connected in series to the blower fan motor. This means that the current running through the blower motor, and its’ speed is therefore controlled by the resistor value. The user chooses a fan speed by selecting a speed which then connects one of the resistors in the blower resistor pack.
Why does my AC blower motor not work?
The blower motor relay supplies power to this motor when you turn the switch to “on” that can sometimes fail. When this happens, you may notice that you will not feel anything blowing out of the vents at all. This may also cause the blower motor to work intermittently.

Why does my AC fan not work at high speeds?
On the low speeds, the fan relay routes the voltage thru the resistor block. When you switch to high fan speed, the relay switches over to supply full voltage from the battery to the fan motor. Tester is right.
What kind of blower does not work on high?
1997 GMC C1500 Heater/AC Blower Will Not Work on HIGH. 1997 GMC C1500 Heater/AC blower will not work on HIGH. I have replaced the black BOSCH relay behind the glovebox, the blower RESISTOR and the blower MOTOR and still cannot get the blower to work on HIGH.
What happens if the blower speed of an AC unit is too high?
If a blower speed is set too high, your AC might not be operating optimally. This is because the evaporator coil will not be able to adequately dehumidify the space in need of cooling. On the other hand, if the blower speed is too low, your evaporator coil is at risk of “freezing.”
How does a high speed blower motor work?
In the highest fan speed state, the blower resistor is bypassed completely and the fan is effectively connected directly to the car’s battery, allowing maximum current to be supplied to the blower motor.
