Heater doesn't work
does the blower still work?? Are you waiting long enough for the engine to warm up?? your heat comes from the engine heat. hot coolant (antifreeze) flows through the heater core (like a smaller radiator) behind the dashboard. the blower pulls air through the hot heater core, making the air hot.
If it blows air, but never gets warm, you should first check your coolant. if you drive your car without it, you will have big, expensive engine problems. If there is no coolant or very low coolant, you need to check for leaks after you refill it. (make sure you get the right kind of antifreeze. autozone can help)
most cars that new dont have radiator caps. Instead there is a seperate coolant tank under the hood. fill it to the full mark, let the car run and watch it. It will **** down the coolant from that tank untill the radiator is full.
If you have plenty of coolant, you may need a new thermostat. sometimes they get stuck. some stick open, some stick shut. It is usually easy to change one and they are cheap. I can't help you much with that cuz its different on every car. on my car, I have to crawl under it to get to the thermostat. hope this helps.
