Buying a used car in the winter, how can i test to see if the A/C works?

I want to be sure the A/C works on a used car before I buy it, but it is only 15 outside right now. What can i do?

Best answer: A mechanic is your best bet. They can hook your car up a machine to test and see if there's refrigerant in the system, among other things.

Take the car to a heated garage.

b1tr0t nails it. Indeed, in modern cars, the A/C is part of the defroster (the idea being to blow *dry* air onto the windows to remove the fog, and A/C units dehumidify as well as cool air.)
