Your J30 is going to be similar to the Q45 and I've had this problem in 2 of my Q45's. In both cases it was the door stuck in the closed position the first time I asked for heat after the long summer. f you haven't already, remove the mix motor and test it with a couple of probes connected to a battery. While the motor is out exercise both doors manually. If the motor tests good chances are it will work when you reassemble the motor to the air box.
