Recently my heater fan has been acting up! When you turn the fan Knob from 0-5 the fan doesn't start blowing at all until you get to 4. What could possibly be wrong?? If the fan motor had a problem wouldn't it not work at all instead of just working on the high settings? Does anybody have a suggestion on what is wrong, any help would be greatly appreciated !!!

Thanks in advance,

sounds like the resistor card may be bad

or the switch...

...it should be checked with a test light. or...try removing the resistor, it's located near the blower motor, and look at it...it's obvious when they fail because they burn up...these fail pretty regularly

Where do I find the resister card? Is this something I can do myself ?Do I need to take the dash apart to get to fan motor?

Thanks in advance for all your help !!
