When I turn the fan speeds 1-3 I get nothing. 4(max) works as it should. This is a 2005 stock lib so nothing unusual in it. I took the blower control panel out and looked it over(just the dash part) and found nothing amiss. The pneumatics work fine and it makes heat, but no blower in the lower speeds. Is there a bank of resistors/fuses somewhere else? I wouldn't think its the motor because the RPM on wide open is where it should be. Thoughts?
