auto heater switch will not run blower have to turn on auto then turn on manual fan and back to auto and it will work in auto.

The auto temp switch on the dash will not activate anything until after you turn on the manual fan switch and then right after turn on the auto switch, then it works as before. The Air conditioner freon all leaked out and now it is empty have not fixed yet.
