SOURCE: 96 cavalier overheating

You have a front wheel drive car so it requires and electric fan motor which in turn requires a temp sensor to tell it to turn on. The sensor should be on the radiator itself. Check that the connector to the senor and the motor are tight and if the wiring checks ok then I'd go for the sensor first.
The reason it cools while driving is the natural flow of air at driving speed.

SOURCE: heat

If this car is remote start GM has a service bulletin out to do a computer flash to correct this problem, it will probably blow hot air in the summer if it remote started if you don't have the computer flash done. Hope this helps

SOURCE: Heat blows cold when car is idling

You have an air pocket in the cooling system. To bled it out you will have to park vehicle on an incline or jack up the front end untill the radiator cap is higher than the heater core. The remove radiator cap and run engine until warm then hold rpm to about 1200 rpm's and top off coolant level until you have no more bubbles.

SOURCE: 2004 Chevy Impala no heat from defrost or heater

No heat is often a symptom of low coolant, usually followed by overheat. There are other controls that regulate heater, but right now, re-fill the cooling system with engine running and heater on high, then check for leaks (coolant you lost went somewhere...you need to determine where) Low coolant will damage your engine. Take care of that first, then if heater still does not work, then do diagnosis on that. (if you loose the engine heat won't matter, will it!)

Why would my heater blow out cool air when sitting still and then hot air when going down the road and then it's not all that hot


Try flushing or blowing high pressure air through the heater core lines. its sludge build up and need to be flushed through heater core only. check antifreeze fluid level. only put in straight antifreeze, do not mix. most people do not know what mixture should be, so be safe and add straight, it will not hurt it, i run 100% straight antifreeze and never had a problem or worry about it ever freezing and cracking my block, heads or radiator cracking.

My 2004 Chevy Impala only blows cold air with heat on. The heater would only keep it a little warm the other day but now only seems to be blowing cold air.


Check in the main radiator with the motor cool that the coolant is full as if the coolant is low there will be no heat in the heater. If it is low you need to check for leaks or head gasket problems. If its full check that the temp guage is coming up to its normal position as the thermostat could be faulty. Then make sure that the heater tap is operating corectly.

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

2006 Chevy Impala Heater only works when accelorater is depressed


Impalas are known for this issue, where the heating won't work properly.... usually caused by trapped air/bubbles in cooling system or slightly low coolant level. Park car so that the right front side is elevated and remove the coolant OVERFLOW bottle cap (NEVER the radiator cap) while engine is running.. This should allow the trapped air to escape. Also add a bit more coolant if needed.
