Rear Window defrost

Do all years just blow cabin air?

Yes all years just blow cabin air. I had one in my 68 Barracuda when I lived in Iowa. Works pretty lousy.

In 75/76? They offered a grid heating element rear window in Darts and possibly Duster/Dart-Sports. Pretty rare part.

I’ve seen the Darts ones for sale here in the past.
