Anyone use Vintage Air

One thing about the Classic system and probably all the others that are heat/AC combined is that you will lose the fresh air vent on the passenger side. When I get to that point I will see if I can cut the fresh air vent part off a heater box and build a wall on the open side to keep the vent. We'll see if that can be done.
Correct, you loose the passenger side fresh air vent, but you gain the ducted and powered bi level vents. My plan is to add a switch to the compressor power line so I can have the bi level vents selected and blowing outside air in with the blower, but not have the ac compressor engaged. That will more than make up for the loss of the passenger side fresh air vent that only brings air in when the car is moving.
