Best Answer

Since the heater core is heated with hot coolant, it could be that the thermostat is stuck and not opening. You may also see the engine overheating in this case. Or, the heater core itself, which is finned like the radiator, is plugged with particles. Try backflushing the collant system. Lastly, if you need to replace the heater core, it disconnects with 4 screws on the passenger side under the dash. They are relatively inexpensive - approximately $25 USD at this time.

When you warm up your car in the driveway cold air enters the cab then as you start to drive down the road warm air enters cab?

hi,most likely you have low coolant level in radiator,at idle you have an air space in heater core,causing poor heat,when you move and engine speed increases, water fills heater core,you get heat,.another possible cause is a clogged heater core,but check fluids first.


What would cause the internal vents to blow cold air when the heat is on?

check both heater hoses under the hood with engine at running temp. if only one hose is hot your heater core is restricted( try flushing it out),m low coolant will also cause no heat since the heat comes from the hot coolkant in the heater core. if both hoaes are hot chances are the blend air door in the interior heat unit is faulty or climate control is not calling for heat.


No Heat on 93 Chevy full size truck Replaced t-stat flushed water through heater core T-stat gauge is 205 Now what?

I guess since you were able to flush water through the core there is no blockage or valve to give you trouble. Are the heater hoses hot when the engine is at operating temperature? that is how you know that you have circulation through it. I am going to assume yes since nothing else you said would lead me to believe otherwise. Now you need to check the blend door in the heater. If it is stuck on vent or AC then you will get no heat. The actuator may be bad or the door may be just stuck from humidity.

What makes heat come and stay in a box?

A very basic answer is: The hot water the engine produces is circulated thru the heater core. The heater core looks like the autos radiator only smaller. The heater core is located inside the heater box. So as the engines hot water circulates thru the heater core the heat will transfer into the heater box. As long as the engine is running and everything is working properly the heater core will stay hot inside the heater box.
