I posted earlier about my 96 Concours blowing hot air. I've had the car to a shop and the tech put the gauges on and said all the readings were at perfect levels and the lines are cold. He seems to think the control head in the dash is bad or the doors in the dash are stuck and not switching over. I don't know if either could be right because when I push from defroster to floor I can hear the doors switching so both seem to be working. Any ideas?
