    2006 Chevy Aveo- heater blows cold air, and engine temp gage shows dead cold, when car is moving. When car is stationary, engine temp goes up to normal, and heater blows hot air. No sign of engine coolant leakage.

    My car (2006 chevy aveo) is also very slow to warm up in cold weather. I noticed that the thermostat would be open (radiator getting hot) when the temperature gauge was barely off the low peg and there was still little to no heat coming to the passenger compartment. I showed this to the dealership, they compared to another aveo which did not exhibit this problem, and replaced the thermostat twice and it did not fix the problem. They now say nothing is wrong!

First....check your radiator...make sure its full. No water = no heat. Have you noticed that the knob controlling your heater has become much easier to move? If so, your cable may have come loose. Disconnect your Neg. battery cable. Remove radio, ac/heater control panel. This usually involves removing a few screws. Find your heater control valve located behind above items. You will see what looks like a plastic box behind the dash. On that box, you will find a cable mounted there that moves a lever back and forth. Make sure it moves the lever when you move your control knob. This is your heater control valve. While in there, look for any loose vacuum lines, connections, etc.

A little common sense goes a long way.
If anyone has been working on car in the same area i.e. radio..etc. this could cause one to investigate possible problems as a result.

1999 Lincoln Continental heater blows cold air while driving


Sounds like your thermostat may be stuck open. When the wind moves in front of your car, it chills the Radiator and drops the temperature. All the other settings for Heat, like ductwork and waterflow are in the same positions sitting as moving.

1989 chev g30 heater fan is blowing yet no heat is there a a switch?


Check the antifreeze for temperature protection.Have you changed it lately? Without proper mix in the winter,it will only blow cold air.
Hope this helps

Would the heater control valve malfunctioning make the engine overheat blowing hot air out the heater one moment,then not blowing the hot air, temp gage spikes 225 plus. The motor takes awhile to heat up...


Heater control valve malfunction will not cause engine to overheat unless coolant is leaking externally...Overheating going down the road can be the result of a few different things...Partly clogged radiator...Insufficient air flow due to possible fan problem...External coolant leak...Make sure fans are operting properly and have cooling system pressure tested for leaks...Gaining and losing heat on the inside of the vehicle usually means system is low on coolant but you must find out where coolant is going

My heater only blows hot air when the car is moving and cool air when I sit at idle. Also the inside window fog up if I try to use the defroster mode 1st thing.


Hi:
Your heating system is dependent on hot coolant to be circulated through your heater core, which a fan blows across, and you get heat. If you only get heat when you are moving, that means that either your engine is low on coolant, or the engine's water pump is not working well. Check your coolant level when your engine is cold.
