Question about Pontiac Cars & Trucks
First thing to check is your radiator for antifreeze. Make sure the radiator is cold before you open up the cap! You can also check it by looking at the overflow tank. If it is full, start the car and wait until it the temperature gauge is warm enough to turn on the heater. Turn off the engine and carefully touch the top hose and bottom hose of the radiator to see if they are warm. If not, your antifreeze is not circulating. The thermostat is stuck closed. You will need to replace it

There is a mix damper inside your duct that controls the heat over heater core and ac evaporator that to your floor and one to your defrost. it is probable an electric actuator, that is not functioning properly. If yu can locate it and manually move it, you might have to remove the actuator motor first, you should be able to figure out your problem, I hope this helps! merry Christmas!

go into your car.... under the steering wheel next to the gas pedel theres a little lever .... flick the switch ... it should be a white lever .... if its not then the lever came undone and it will be a black and silver switch..... that should probably fix it ... i had the same car with that problem

If your "Check Engine" or "Service Engine Soon" light is on, you need to have that checked out first.
If not, the next thing you should check is your engine coolant level. (Antifreeze) If the coolant level is low, the engine coolant does not circulate through the heater core and the the heater doesn't work. The coolant level could be low for a number of reasons including a leaky hose, water pump, or head gasket. In any case, if it is found to be low, you need to find out why.
If the coolant level is OK then the thermostat function needs to be checked to make sure that the engine is reaching operating temperature.
If all of the above checks out OK, then the heater control valve and/or the blend air door in the HVAC housing needs to be checked for proper operation. (NOTE: some cars are not equipped with a heater control valve)
