heater on economy or air cond for heater?

which is better for the heater to run on in the winter? the reason i ask is because if i have the heat on economy it pulls air through the cowl and you can hear it when near the outside of the car and its loud, but it doesnt seem like air conditioning does that, so what can i use or can i use both?

Re: heater on economy or air cond for heater?

When you have it set on max, the air door to the outside is closed (same as recirculate).

Economy prevents the A/C compressor from coming on.

When you set it on defrost, the compressor also comes on.

In the winter, if it's cold enough, the compressor will not come regardless of setting until the underhood temp gets high enough to raise the pressure.

So go ahead, put the selector wherever you like. But heat works best when it comes out the bottom, which is the economy setting.
