Bad vac line or cable to your vent controls. There is a door to your heater core that is supposed to closed when ac is on-yours is not. A place that does ac repairs can check it out for you.
Check for a vacuum leak either under the hood or under the dashCheck the vacuum actuators under the dashCheck the selector control Defrost is the default for this system
replacing AC air intake Filter is rigth side, under glove box.
Check your vent pipe. Does it vent to the outside? If so, is it blocked? Is the vent pipe breached? The vent is the most likely cause.
