Stop in for a cup of coffee

Oh, and another cold weather adaptation I made on that old ‘70 Duster to get more heat inside in Winter. If you notice, the cowl grill vent at the base of the winsdshield is covered in black magnetic vinyl with just small slots for the washer squirters.

By doing this and opening the inside passenger floor vent, it allows for a recirculating of the inside air across the heater core making it far warmer inside and making the defroster more efficient.

The same can be done on AC cars to make the cooling more efficient in Summer too.
