Dash area cold air leak-source?
I have cold air leak around the radio and heater/ac controls. it is most noticable when teh fresh air vents are closed and dash and floor controls are open and blower is set to 2 or 3.
I suspect three things at this point. The heater box or duct has a leak or a "cold air" flap is not closing.
Is there a cold air flap that contols outside air from even entering the system? Perhaps outside air always flows through into the system.
Not a major issue. just irritating? Any heating and cooling experts out there?
Thanks,
