My heater/air conditioner blower fan makes a kind growling noise & only runs at
low speed, Dealer suggested Blower motor resistor $94.00 later installed didn't
help.Pulled blower out plugged into power held it off floor works great, re-
installed no speed & same growling noise, loosened mounting bolts let it drop
down about 1/4 in runs fine tighten bolts no speed & same noise
Sounds like a power loss in a wire or component or ground. May even be the switch.
