When I put both black levers to the right, I can hear the fresh air fan blowing but the airflow out the defrost and dash vents is quite minimal. The fan does work on all 3 speeds.
Similarly -- I just reattached all my heat, and even with the booster fan going in the engine compartment, there is just not much airflow. The engine compartment hose and the flapper --> firewall hose are new, the HX's are SSIs in good shape as is the rest of the engine compartment plumbing. What level of airflow should I expect? What should i check or refurbish to get better CFMs? |

Be sure nothing has fallen into the windshield airvents; mine had accumulated a dozen parking ticket stubs. May not be easy to see, but a wire with a hook on the end will find most of them. If there's just one or two, you can hear them vibrate when the fan is set to high and your driving at 50 - 60... (IMG:style_emoticons/default/smile.gif)
