HEATER/AC AIR FLOW QUESTION
AC & HEATER BLOW AIR ONLY OUT LOWER FLOOR VENTS. NO AIR BLOWING OUT DASH VENTS OR KNEE HEIGHT VENTS. FRONT DEFROST ALSO DOES NOT BLOW OUT WINDOW VENT. WHY? WHERE SHOULD I START?
Is it the blower motor? Can you control the speed of the air coming out of the lower vents or not?
Sounds like a vacuum line issue.
I can control the air flow.
