Well I want to get these working correctly.

When I pull the heater level all the way up, hot air just "oozes" out into the cab. When I move the fresh air fan lever over, it doesn't seem to work or even turn on. The airflow doesn't increase... Also, the other two directional levers don't seem to work either- the hot air oozes out of all- defrost, center and down. Am I missing something?

Is there a diagram that shows all the wiring and correct tubing for the heater and fan? Where do I start? (IMG:http://www.914world.com/bbs2/html/emoticons/huh.gif)

Turn the key on and pull the heater lever all the way up. If the auxiliary heater motor works, you'll hear it running. If it works, check the flappers to see that they open all the way. Check the hoses from the flappers to the heater tubes. There are also two hoses behind the speaker grills that are sometimes damaged or missing.

The fresh air fan is independent from the heater system. Once again, turn the key on, push the top knob on the dash control to the right. If it works, you'll hear it. Its susposed to have three speeds.
