Should I let air flow in from the front of the car or the back of the car or leave the lever in the middle?

Question

I'm having defrost problems on my car and the windows keep getting fogged up. Before it was ok, but then somebody moved the lever. Which end do I want the air coming through that will also stop fogging up my windshield?

Answer 1

In the summer time, a good way to defrost the windshield is to put the a/c on for a few minutes with the flow set on DEFOG or DEFROST and have the recirculation control set to keep the outside air from getting in. The opposite is for the winter time - allow outside air in, set the heater on high temp - still keep the flow to the windshield. Hope this helps.
