Question about 2006 Chevrolet Aveo

1 Answer

A/c and heater problem A/C will sometimes blow cold air for about 20 seconds then start blowing warm air. Then when using the heater it will blow warm air for about 20 seconds or so then start blowing cool air. I can turn the temp knob from one side to the other or turn the fan to off and it seems to help the problem for a while. What could be causing this problem?

Sounds like you may have developed a leak in the system, when the pressure in the system is low it will cause the compressor to cycle off and on. Have you tried to charge the system? P.S. Dont know if you are aware but hte compressor kicks on when the heat is on as well as he AC.I hope this helps and good luck !!

You need to fix the coolant leak, then refill and bleed cooling system, then you will get heat and cure overheating problem too

My yruck only blows cold air wont blow warm


Could be the air flaps of the heater unit are set incorrectly or not working at all or possibly the heater radiator is blocked or semi-blocked or perhaps there is something wrong with the heater hoses or the heater water valve if one is fitted.

These things need checking before a cause can be established.

I am sometimes called upon to flush out a heater radiator. Sometimes it works and sometimes it doesn't and sometimes it causes a leak and the heater radiator must be replaced. Not an easy job on many vehicles made in the last couple of decades..

Heater not blowing hot air


Hi Chris, sounds like your thermostat may be worn and not closing all the way which would cause your engine to run cool at times. If you have a temp gage it should tell you if the engine is actually warming up or not. If not I would replace the thermostat.

I have a 2001 silverado 5.3l 4x4. My heater blows warm air sometimes and then blows cold air. My thermostat stays at a steady 200 degrees when warmed up. I filled my coolant and didn't have any leaks, does...


Sounds like air in the cooling system. Try taking radiator cap off and letting the vehicle run with heater on high. As bubbles come out add coolant. This may take 20 minutes to a half hour.

Engine heats up but takes a long time for warm air to blow. Once working, the thermostat works fine. Sometimes, warm air starts to blow and then goes cooler.


low fluid level or heater control valve may need replace..check hoses going to heater core...if cold...between heater control valve and heater core..replace control valve

When driving, heater blows warm air. When idling, cold air.


check your anti-freeze level, I'd bet that you're a little bit low!

Heater blows cold air


With the car warmed up,feel the heater hoses,are they both warm/hot near the firewall in the engine compartment?If they are both warm/hot,then the heater core should have circulation through it and it may be a "blend door" issue in the heater a/c assembly.If they are not warm/hot then the heater core could be dirty and plugged up and needs to be flushed.
If the above does not help,a drain and vacuum of the cooling system and vacuum refill will remove any trapped air.
Sometimes,clamping off the top rad hose and holding the engine rpm at 2000 rpm will force trapped air out of the heater core.(Watch temp gauge when trying this)
Lastly,a NEW thermostat doesn't mean its working correctly.
