The A/C system and the heat system are not connected except that they use the same fan to distribute the air. If using your heat resulted in the failure of your A/C the issue is likely to be electrical. You didn't tell us if the fan is the issue or something else. Can you hear the clutch engage when you turn on the A/C? Is the fan operating in either mode? Will the A/C come on even if the selector is in heat mode?
