My heater in my 1993 Chevy Caprice Classic suddenly stopped blowing hot air. I was trying to defrost my window and I was unable to. It still feels hot when I put my hand over vents but it's not blowing anything out. My question is what could this be and how much to fix?

Here is the wiring diagram just in case you can test for power and see where you lose it at.
