- Some of the main causes of weak airflow are:
--Mold or mildew can accumulate in the evaporator core, when this
happens air will have trouble reaching air vents.
--Your hose could of come lose, the blower hose that supplies air to
unit is off.
--The ventilation fan is broken, no air will blow well or at all.
--Your seals: blower house seals, core case seals or evaporator seals,
if seals are compromised the air flow will diminish. Come by Ricks Auto Service
