Most likely a vacuum leak. First check if the bigger ac line below/behind the drivers side wheel well is cold and the small one is hot. If that's ok its probably got a vacuum leak. Pulling the side panels will allow you to see the vac hose that operates the door that switches air flow from the heater to the ac. there is a connector on it. Pull the connector apart and suck on the hose to the actuator. If the actuator moves the door you have a vacuum leak somewhere. Good luck finding it. I havent found mine. Sucked on the hose w/ a Golf tee in my mouth and pushed into hose w/ my tongue. Kept door in ac position, but my evaporator isn't getting cold. One more thing to fix.

Depends on what you mean by heater will not work. If the blower motor will not work, it can be a blown fuse, bad blower motor, bad blower motor switch, or a defective blower motor resistor pack. If you mean that the blower motor works but there is no heat, then it can be a clogged heater core, thermostat stuck open, or defective heater control valve.
