The blower only works on high. Are there some fuses, resistors that control the lower speeds that I should replace? Have others found the control know to be the problem? Do you think it's the motor itself? Again, motor works fine but only on the highest setting.

Thanks

 

From what I searched on the forum, it seems like the resister is more likely the cause. Where is this resistor located and is there a test that I can do on the resistor to prove it is the problem?

 

Sound like blower motor resistor. If you have a multimeter or ohm meter, you can test the resistance. But, even without testing, usually it will be the resistor.

 

Thank you all. This was a quick fix, the old one tested bad on my ohm meter, purchased a replacement and bingo - all 4 speeds on the blower motor work again.

Thanks.
