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?

If the blower motor isn't working? Check for voltage and ground at the blower motor, purple wire is voltage, black is ground. Voltage for high-speed comes from fusible link. Voltage for lower speeds is fuse protected.
