I drive a 1968 coupe 289 all stock?
there is a vent underneath my dash to left of the steering wheel. and when i drive it lets Air into the cabin. this is fine during the summer but in the winter it makes the heater obselete. i have looked and i see no way of closing of blocking into from allowing air in. i could put tape over it but there must be a way to close the vent. and what is the purpose of this vent if it lets outside air in.
any info appreciated
