It could be, low on coolant due to a leak in the system, a faulty thermostat that is stuck open, a plugged up heater core or a faulty temperature blend door actuator. With the coolant reservoir full, engine running and warmed up, open the hood and feel the heater hoses with your hands. If one hose is hot and the other hose is warm or cool the heater core is probably plugged up. If both hoses are warm or cool the thermostat may be stuck open. If both hoses are hot the temp blend door actuator is probably not working.

Does a broken thermostat cause the defroster inside your car to put frost on your inside window instead of remove it?
If the defroster is blowing hot air and it is still leaving moisture on the inside of the windshield, the heater core may be leaking coolant causing that condition. If the defroster is blowing cold air it could be the cooling system is low on coolant, or the thermostat is stuck open or the heater core is plugged up or the temp blend door has a malfunction.

Why is your 2003 Chevy S10 extreme blowing cold air from the heater?
The most likely cause is that your air mix door has malfunctioned, and will not change from ac to heat, but it is possible that your heater core has become blocked, or that there is a water valve in the line that has become stuck.
1989 Chevy Corsica has no heat or defrost or blowing at all why?
If you feel no air blowing at all (when you are not moving) then your fan is not blowing. If it is blowing air, and it is cold, when the heater is on, then most probably your heater core is leaking, or is clogged. These are easily replaceable and go bad all the time in older cars.
