The heat stopped working on one side of the car. The drivers side still blows out warm air but the passenger side blows out cold air. Also the defrost never shuts off. It constantly blows cold air out.

It sounds like you have a vacuum leak causing the defroster to stay on. Check under the dash. The air flow vents are actuated by vacuum. Check for disconnected, dry rotted, or broken hoses. As far as the heat issue, do you have a dual climate control?

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
