I have a 1973 chevrolet camaro with 138,000 miles. When the key switch is turned to the on position air comes out of the vents. not warm of course, since the car isnt at operating temp. However when I start it to get to hight temp and check for hot air the air no longer comes out of the vents(no hot or cold).
