Question about 2005 Chevrolet Aveo

Open Question

2005 Chevy Aveo, 4 Door Sedan. My A/C slowly stopped blowing cold air, to the point it was only mildy cool temp, "not hot nor cold or warm, just a mild cool. Nowhere near cold enough to cool off the interior of the car. So, I went to the dealer and had the air conditioner checked for leaks and freon added at the dealership and it still is doing the same thing. I do not know if it maybe the temperature sensor or what. I noticed today the cabin air filter was filthy, so I changed it. But no improvement. I live in Arizona with over 100 degree temps. really need to get this things working. Any ideas on what the problem maybe? It does blow at a very mildly cool temperature, but now where near cold enough to cool the car interior or the people in it. Please help? Thank you...

SOURCE: Heater does not blow out hot air, it is mild warm,

check a few things 1. check to see if your truck has built pressure in the radiator when hot. if not change the cap.. make sure you have a good thermestat in the truck.. last you can disconect the two heater hoses and see if water flows freely. if all else failes. make sure the water is moving in the radiator by removing the cap and allowing it to warm, when the thermestat opens you should see the water move if not the inpeller in the pump could be broken.. if all else fails change the radiator

SOURCE: I just had oil changed at Xpress Lube. They said I

Filters can be deceptive - as well as quickie oil change joints!! While a dirty cabin air filter will not affect your mileage or performance, a dirty air filter will rob you of power and fuel mileage.Modern air filters can take a decent amount of abuse but, if it is a disposable, they can clog up and not LOOK bad. Replacing a disposable air filter with a cleanable air filter ( like K&N or Spectre) will improve your engines performance and lifetime span and is something you can do without paying somebody to do for you.Cleaning your air filter about every 10 oil changes will assure maximum performance. Some will say this is too frequent and very well may be, depending on your local terrain ( dirt roads, sand,farming,city, etc.) and you'll have to be the judge on that. Quickie oil changers make their money on peripherals - filters, additives, etc. and many times will tell you a filter needs changed when it doesn't. The general rule of thumb on filters is this;
If you hold the filter up and look through it at the sun or bright light and see light through it then it is still good, but if lots of junk falls out of it then it's time to replace.

2000 caddy Seville ...after starting and engine warm turn on the heater and it blows cold air. Fan works / waiting for hot air and then all the sudden it kicks in. Engine at normal temp


Low coolant, if there is an air pocket in the engine it will make it to the heater core. Once there , the air coming out is cold/cool. Once the coolant fills the heater core, it gets hot. If the coolant is fine hot or cold, then have the HVAC system scanned.

I have a 2003 chevy impala. Just recently come acrossed in issue where the heater blows nothing but cold air even with the temp gauge going as high as it can get. Weather its at an idle or being driven....


providing your coolant is full cause low coolant will cause no heat
and your temp gauge is normal in the middle then most likely u have a bad blend door actuator usually on the passenger side

One of two things has happened. Either your coolant has gotten really low (easy enough to check) or you heater core is starting to plug up.

Chevy 2005 tahoe z71 blows cold air in back but hot air in front


Just got an answer from Chevy Dealer. When you replaced the battery it loses its memory as to where the door actuators were (the flaps that control the heat and A/C).

The fix:
Turn everything off and let the car sit overnight. The computer should reset itself during its learnings process.
In the morning turn on the ignition and let the car run for a few minutes before turning on the climate control.

If this doesn't work, plan on 1-1.5hours of labor for a technician to reset the actuators at the dealership.

Good luck.

It could be the electric fan is going on too easily.
The radiator and hoses should be almost too hot to touch.
And when cold, the fan should not really do on at all.
But the thermostat could be opening too soon also.
There are two hoses to the radiator, and when you start a cold car, only one should slowly get hot.
The other should stay cold until the thermostat opens, after the engine is good and hot.
If both start slowly getting warm at the same time, then you need a new thermostat.
And also make sure you have enough coolant in the radiator.

No heat air is blowing cold


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 worm) 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 to flush the heater core.

Air Conditioner stops blowing cold air when vehicle is not moving


plus one on the cooling fan problem. if it was low on charge then as you slow down, condensor temps and line prressures would raise therefore it would cool at low speed and and not when moving since the incoming air would drop system temp,reducing line pressure and then cusing compressor to cycle. the auxillary cooling fans must be on whenever a/c is on, if not, thats your problem. get this taken care of because if you get stuck in traffic, your engine will overheat also if fans are not running
