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? |

I just rebuild the air box flapper box in a super clean no rust Ca. Car but the rubber was dried out in the air box and gone. Un like the air box in my 6 that was still soft and perfect. Have you looked at the flappers? If you air box has a gap in the fan to the body it will not work good.
