check the fluid level in the tank or radiator. Check the top radiator hose when the car is warming up, is it hot? If not it might just be your thermostat that needs to be replaced. Or it could be that your heater core is plugged up. You don't say how old a car this is in, some times you can take off the heater hoses and connect a garden hose to it and back flush it and get some of the junk out of it, just don't turn the hose all the way or out can blow a hole in the heater core, then you have a mess. If you are not handy, you can go to some place that power flushes the cooling system and that may fix it also. Just hope you don't have to get a new heater core as they are a pain to put in in most cars and costs a lot to have some else do it. The core doesn't cost much but the labor is a lot.
