1999 Ford Escort SE basically no air through vents,
Changed ac/heater blower motor and resister. Assumed blower was bad. I can
hear physical movement when selections made to where air flows.
Compressor kicks on. Plenum? flap over blower motor moves when fan turned
on. I understand no cabin filter on this model. DIY here. No great knowledge of
cars so simple is better. Thanks Joe Arwood
