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? |

QUOTE(rhodyguy @ Oct 4 2010, 10:50 AM)  where do you have the bottom lever positioned? That (red) lever should only effect the fresh air flow, not the heat air flow, correct? When i'm trying to get heat out of the dash, my config is: top lever -- full left middle lever -- full right bottom lever -- full right floor lever -- up Whem i'm tring to get fresh air out of the dash (not heated), my config is: top lever -- full right (the fresh air fan is on) middle lever -- full right bottom lever -- full right (although i don't think this matters) floor lever -- down I checked, and the plastic wheels that open the dash vents are in the open position. |
