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? |

Take a close look at the paper tubes that the air flow in and see if there's holes. Check the ones behind the speakers too.

Does anyone know the ID of the required tubing? Has anyone had luck sourcing it at a FLAPS or hardware store? I'm getting tired of mailordering parts from CA every week. |
