Re: Heater Fan doesn't blow on low
I’ve got medium and high now. On low the fan doesn’t blow at all but the resistor turns red. Also turns red on medium but the fan also blows.

Re: Heater Fan doesn't blow on low
You're making progress. The bearings could be going out on the blower motor, or your squirrel cage fan maybe rubbing on something. If taking the blower motor out I recommend treat the rubber hose that goes between the motor and the evaporator casing with care, because it is not reproduced. Mine was cracked and I restored it to reasonably good condition with super glue and black RTV.
