My heater works fine on a hot day but as soon as it gets cold it refuses to kick in.Air cond and all air vents work fine and all flaps seem to open and shut


Scott, you do not say if your heat gage gets to normal operating temp., First thing to check is to ensure coolant level is right up.
Possible bad thermostat.

check your owners manual and see if you have an inside cab air filter for the heater/air cond. When they get clogged, they restrict the air flow.

Your closing in. There is a motor that will open the heater core venting to allow it to blow into the car. Get a heater core install picture from your auto parts dealer or car dealer for specs of where and how it is driven.

Heater does not blow hot air


It seems as if your water valve that is open to divert water from the water jacket to the heater core is not working. It also could be a blocked heater hose.

Air flow out of A/C (HVAC) seems to be partially blocked. Noise increases with increased fan speed settings, but flow barely changes. Even on maximum setting the flow is not enough to reach driver or...


One of the Actuators for the doors inside your dash that controls and diverts air might not be working correctly. You may have to either replace the Actuator or Replace the A/C Heater Control. Your vehicle does not come with a Cabin Air Filter.

2003 Grand Prix not blowing hot air. Does the heater coil need to be replaced? If so where is it located?


If the heater coil was bad, it would be leaking radiator fluid... probably into your dash/floorboard (depending on where it is installed in your model car). There is a switch that diverts the hot radiator fluid through the heater coil when you want heat. There is also an air diverter valve that helps to mix the hot and cold air. The fluid valve is controlled by the A/C settings control. The one that you use to choose between heater/air conditioner/vent/ defrost. The air diverter is controlled by the temp mixing controller. The most simple explanation is that one of those valves or the controller of one of those valves is not working. If the hot water cant be diverted through the heater coil, the coil can't exchange the heat (warming the air). If the air diverter (hot/cold controller) cant move to add heat, then all you will feel is air from the vent side (from outside) or from the A/C cooling the air.

I would guess that its either a controller or one of the valves themselves. Odds are, it is a controller. That tends to be what malfunctions first.

Heater/air cond blower only works on high. any


It is the Blower Motor Resistor located behind the Glove Box on the dash. Remove the Glove box to access. It is mounted against the fire wall. This is a common problem. My 2002 did the same exact thing.
1. Disconnect the negative side of Battery.
2. Disconnected the Electrical Connection to the Resistor.
3. Remove the bolts/screws. I believe they have 8mm heads, there should be 2 of them.
4. Replace with new one.
5. Reconnect the negative side last.
6. Test System before putting the glove box back in!
7. Enjoy the CONTROLLED HEAT!!

Heater blows cold air. does not get hot and defroster does not work


UNDER THE HOOD TOWARDS THE FIREWALL YOU WILL SEE A HOT WATER CONTROL VALVE.. IN LINE WITH HEATER HOSES... CONFIRM IT CHANGES WHILE SOMEONE ELSE IN THE CAR CHANGES FROM HOT TO COLD.. IF DOES NOT CHANGE THEN THERE IS YOUR PROBLEM...IF DOES CHANGE THEN THE NEXT COMMON PROBLEM IS WHAT THEY CALL THE BLEND DOOR ACTUATOR...THESE ARE LITTLE DOORS IN THE DASH THE DIVERTS AIR IN THE DIRECTION YOU CHOOSE...THIS IS A MAJOR JOB TO REPLACE.. NOT FOR THE DIY
