Default Fan Blower?

I just keep coming up with new ways to annoy you all

The air movement in the passenger compartment is AWFUL. The difference between low and high on the blower is not much. When I turn it on high, it makes more noise, but the airflow is barely faster.

What do I need to troubleshoot/replace here to get good amount of flow here? Keep in mind this is just "VENT", no A/C (thats another project -- R-12 is RIDICULOUS and to convert to R-134 seem like a PITA)

Summer's a' comin' and I'm already dying!

Question Re: Fan Blower?

The door(s) that control airflow in the system might not be "flipped" right to get the best airflow. This can happen due to the age of these cars.

Have you ever heard a "thunk" or "whap" sound from under the dash? That might be an indication this is happening.

I only hear that sound when turning the system from "OFF" to "VENT" which I figure is normal. Ill look at those doors though...

Exclamation Re: Fan Blower?

FWIW, the R134a conversion is not that hard. And there is a complete procedure on the site. (Surprise!)

So I am back to revisiting the blower now the the car actually runs properly :-)

Scott - You mentioned in a previous reply the "doors" may not be opened properly. Where are these doors? Behind the dash? Do I need to take the dash off to access them?

And in reply, no, there is no big "whack" or "thrump" when turning the vent on.

Default Re: Fan Blower?

I replaced my blower 2 weeks ago because it was noisy on low speed. The shaft/bushings/bearings? wore out and it needed to run on high speed to balance out.
For about 30 bucks it can be purchased at Autozone and it is the entire assembly with the motor and blower wheel.
Clean the OTHER SIDE of the EVAPORATOR COIL, you will may surprised how clogged it can get.
