Question about Chevrolet Cavalier
Very little heat coming from any of the vents/defrost/heater the fan works on all speeds just that the air is not very hot more luke warm than anything
Need to check the coolant level to ensure that it is full. If full, check the hoses going to the heater core. Both hoses should be hot. If one is much colder than the other, you have a stopped up heater core. If that is fine, check to be sure the engine is getting as hot as it should. A stuck open thermostat will not allow the coolant to heat up enough and not blow hot air. If all that is good, check the blend door under the dash. It may be getting stuck in between the hot cold positions and not allowing all the air to flow over the heater core.

SOURCE: air conditioning and heating
have the water pump checked out, i had a van that did the same thing and founf i had a bad water pump it fixed the problem.also check the blower motor to make sure its working right by tapping on it while you have the car running. the car will survive dont worry its going to be one of those two things im pretty sure.
