My mother in laws 2002 century blower only works on high..


It is not the blower motor.
On the 2002 model, I am showing an HVAC control module and a blower control processor. The control module handles the temp control and blower speed, and the processor contains the resistor for slower blower speeds.
Which component did you replace ?

The fan speed switch for the heater/ac will not work on the two lowest speeds, only med to high. Went to a salvage yard and got a replacement one, it does the same thing. Apparently there is something...


You need to get the blower motor resistor replaced.This is your problem.It is located by the blower motor.There will be a connector from the blower to the resistor.The resistor controls the fan speeds when you turn the knob on the control head.The blower motor is on the passengers side under the dash.Hope this helps.Good luck.

Heater blower stopped working?


Hello,
You may want to try your fan on all speeds. If it will work on high, you have a bad resistor for the fan motor. ( high speed doesn't go through the resistor ).
If it doesn't work on any speed, I would check the following;
1. Make sure the fuse isn't blown for the fan blower motor.
2. Check, or have checked the wires between the fan control switch and the fan blower motor.
3. Have the fan control switch checked.
4. Have the fan blower motor checked.

I hope this helps you.

Heater fan motoer only works on high setting?


many of the heater blowers use a resistor type switch to adjust the fan speeds, when the switch goes bad only the high speed will work. the resistor is usually located in the airflow in the heater box under the dash. find it , change it (it just plugs in) and it will work again

for the fan blower motor it could be the resistor or the fan control speed control switch is bad.for no lights replace the DRL RELAY for the lights. for the heated seats check the fuses.

Heater switch to operate the fan inside the car


It's usually caused by a faulty fan speed control resistor. If you can follow the wires from your switch, they usually connect to this resistor and in turn the resistor is connected to the fan. I found my fan control resistor on my GM car inside the fan cavity. I removed the fan and located it inside the housing. This resistor gets very hot so it is placed close to the fan to cool it. Good luck.
