Does the air temp motor move when you flip the Logicon temp selector from hot to cold???

With the key on, but the engine not running, you should hear a small motor moving when you move the air temp selector.

If it doesn't move, you may have (in most likely order)
a bad Logicon
a damaged or disconnected linkage on the air temp motors connection to heater
a loose plug between the logicon and the dash (found above the accel pedal).
or a damaged or broken air temp motor.
