There is a part called the air temperature blend door inside the air ducting of the dash, it controls the air temperature by moving between the AC Evaporator core and the Heater core, it is broken or the electric actuator is defective that moves it or more commonly both are defective. To replace these parts requires the dash be removed from the truck. This is a VERY common problem with 1995 up Explorers.

2002 pontiac aztect overheating has new thermostat and water pump


Try removing the thermostat and reverse flushing the motor, Actually try flushing in both directions, this will tell you if you have a circulation problem but 1 thing you should know is that the water goes in the water pump and out the thermostat, try running it without the thermostat and check your water flow

I have a 2003 alero with the v-6 what happened was driving down the road the heater works fine. then all of a sudden it was blowing cold air and the temp gauge started climbing. it started blowing how air...


Sounds like the water pump is cavitating . Replace water pump. Check coolant level also. Open the bleeder valve usually located on thermostat housing to remove air from system. close valve when coolant is present while filling. close radiator cap and top off recovery bottle to correct level. These engines are prone to overheating, do not let temp gauge get in the red.

After 40 mile ride engine started to overheat. Heater blew cold air.


when the heater blowes cold you are low on anti frezze, the system is designed so that when the system gets low on coolent the heater will blow cold it is a waning for you to know some thing is wrong, i dought it is a head gasket but it might be, you need to have some one pressure test the cooling system, my first thought is to have someone take a close look at the weap hole on the water pump. we see alot more waterpump leaks then head gaskets on the jeeps.......good luck

ZaThe car has water and has been running fine until


Hi the first thing you need to check is the thermostat if this stays closed then the coolant wont circulate around the engine properly and this will cause it to over heat.

to test the thermostat you need to remove it from engine and then have a look at it so you can see that it is closed in the middle then boil some water and place the thermostat into the boiling water leave it in their for couple of minutes then take it out and have a look at the middle part it should have now opened up to allow water to pass through if it dont open then it will need replacing.

that is the most likely cause how ever if the thermostat is ok then it will be one of the following faults

it could be

faulty water pump
faulty coolant pressure cap
leaking coolant pipe
or worse case it could be head gasket failure

if it comes down to the head gasket being at fault then you need to check thermostat and water pump as the main cause of head gasket failure is due to one of these faults.

try this first get the engine who by leaving the car running then turn the heater onto hottest setting and turn it on if the heater blows out cold air then the thermostat needs replacing if it blows out hot air then the chances are the thermostat is ok and you then need to check the other possible causes i listed.

let me know if you have any problems ok

MY 1998 FOR TARUS HEATER WILL NOT WORK.WAS DRIVING


It is most probably the problem with blend door or blend door actuator. But just in case I would suggest to follow the entire procedure:

First you have to identify what causes the problem.
To do this you have to:
1) When engine is cold check the level of coolant. If it is low fill it up.
2) Start engine and check if engine reaches regular temperature. If your engine is not heated enough it means your thermostat does not work properly and should be replaced
3) If engine temperature is normal, then check the temperature of pipes that go to/from heater core. These pipes are located up the fire wall (easier access is from the passenger side). If pipe/pipes are cold (even engine is warm) it means you heater core is plugged and should be flushed. Keep in mind, flushing the whole cooling system is different from flushing heater core.
4) If pipe/pipes are hot/warm, turn off the fan, switch controller to the hot position, wait for 3-4 minutes and turn on the fan. Note if the cold air blows first or warm air blows first but it cools down in 5-10 seconds. If the air blows cold than it is most probably the problem with blend door or blend door actuator.
5) If air blows warm first and then cools down, then while running engine and remaining the transmission in PARKING position, press on the gas pedal until your engine reaches 3,000 RPM. Check if your heater blows warm/hot air. If it does, then your water pump does not work properly and should be replaced. If the air still cold, I would suggest flushing the heater core.

The bottom hose will not contain an air pocket. Check your water pump. When the engine is cold, take off the radiator cap and start the engine. When the engine temperature indicator shows normal operating temperature, you should be able to see the coolant moving through the radiator. If not, the water pump is not working. Could be a missing belt, could be a bad pump.

My heat is not working. Its throwing out very cold air now. It happen before and i replace thermostat and blew air threw heater core. I blew air threw heater core the other day now its throwing out real...


It sounds like your heater core is stopped up, or be sure your coolant is flowing, and picking up heat from your engine...Thermostat, water pump, etc.

Heater blowing cold air


My 2005 Nissan Sentra 1.8s with 55,000 mi. blows cold air from the heater. Coolant not circulating in engine. Lower hose stays cool to touch. Both heater hoses cold. Changed thermostat - didn't fix it. Coolant not leaking or dirty. None in oil - no oil in radiator. Changed worn water pump belt - pump spins freely with no noise or resistance. Cooling fans come on after warm-up. Temperature gauge stays in normal range then jumps to hot and back again. Coolant good to 10 below - didn't freeze here yet. No other problems or repairs to car. Afraid to drive and make worse. Help!
