You can't run the A/C and not drive the car for long. At idle the alternator isn't putting out enough and you are using up power from the battery. If you do have an '82 then you shouldn't have the Ducey, it is more likely the Motorola unless it has been changed. You could make sure all the electrical connections are clean and tight, the belt to the alternator is not loose, and the battery is still good (if it is over 5 years old it is time to replace).
