The fresh air blower on my 71 works very well while driving with the RPM's up, but sitting at idle.... the speed and quantity of air is barely dectectable. Shouldn't the fresh air blower speed work the same regardless of RPM?
Suggestions or advice is appreciated. Thanks!! |

The output of the fan housing has small metal flappers. Maybe yours are stuck open or missing. These are meant to prevent the blower from pushing air into the fan housing at low motor speeds.
