Rear window defroster

The ones with the recirculating interior air non heated don’t work nearly as well as the heated grid.

The one in my 68 Barracuda has two round vents. Takes a long time but you’ll start to see two unfrosted circles eventually.:rolleyes:

I added one when I lived in Iowa. It was better than nothing… barely.

Not very common in SoCal at least. Rarely see them in cars from around here.
