Does using the defroster affect gas mileage?

Yes, it will decrease fuel mileage slightly. Reason being is that on all modern vehicles when the defroster is run the A/C compressor is also running. The compressor is driven by the engine and this extra load on the engine will require slightly more fuel. The benefit provided by the defroster far outweighs the slightly more fuel you will use.
