#82 of 144 Wheres the Heat
Oct 18, 2010 (1:56 pm)
I bought a used 2008 Chevy Impala LT and liike it so far. I do have a question. Now that it is getting colder I notice that if I turn the heat control knob to anything less than 3/4 of the way from the HOT setting that the air temp cools down pretty quick. Is this normal and what might be wrong and possible fixes. does that knob control the water flowing to a heater core or a vacuum solenoid or something simple?

I also have a 06 Impala that does the same thing. The heat also seems to lessen when I am going under 50 mph. Anything over that speed the heat blows hotter. I do not use my remote start.

Got air in the coolant system? Not easy to get out and can affect cabin heating.

Have you taken your vehicle in to the dealer? If not, I would definitely recommend starting there! I look forward to your response.

#86 of 144 2008 Impala heating & A/C

A/C & Heating
Hello, first I cannot send this in the allotted characters.I can see by the forums on this site that a lot of people trust in Edmunds. I think the info is not known to Edmunds nor thousands of Chevrolet owners & prospective buyers. This pertains to my 2008 Impala & possibly many other chevys. I told Chevrolet about this last year & last week. The COMPRESSOR runs almost constantly in HEATING & A/C situations. The facts are: SITUATION #1 A/C in the off position, right knob in the vent position, two thumbwheel slides in the mid position calling for heat, air flow in the off position, air in the recirculation mode. The outside temperature drops & more air flow is needed. Switch the fan knob to the first higher position or higher & the outside air automatically switches on. Switch the air back to recirculating air and the A/C kicks on with tne A/C lite off. Push the A/C button, the A/C lite comes on (as it should). Push the A/C button again and the lite goes out as it should but the A/C does not turn off. The only way to turn the A/C off is (1) by pressing the outside air button to the on position or (2) turning the fan knob to the off position. I would think that people living in areas where the temperature drops to freezing would switch the recirculating air back on because they don't want freezing air coming into the car. SITUATION #2 Temperature in the 60's. A/C off. Right knob in the vent position. Heat switches off. Fan knob in second position and outside air open. You're behind a smoky bus and the temperature is dropping. Push recirculating air on & the A/C kicks on. The average person would then slide the temperature controls for heat. They will get heat but also the compressor would be running. This is a waste of gas and waste of power. I sent Chevrolet this info and they told me that's the way it's designed. They asked me what I wanted from this. I told them nothing because I am aware of the situation and I know how to control it. I think all the owners of the models that this is happening in should be notified about it. The only time the compressor is NOT running is when outside air is open and A/C off. Please let me know what you think about this. Thank you for your patience. Mike Vasko

Since heating and a/c problems seem to be a universal problem with the newer Impalas...wouldnt you think this is a design flaw caused by Chevy and they should correct it? I still have no heat when the car is idling or when the RPMs go under 2..like slow driving. I just purchased this car in October and of course the limited warranty expired as soon as the weather got cold enough for me to use the heater. I do not feel I should have to pay out of pocket to correct something that the designers of the Impala screwed up on. ( I know 5 people who own 2004 or newer Impalas and they all having heating problems)

Bhender....same problem with my 2004. I find I only have heat when my car is reving more then 1 on the tach. When I have to sit at a stop light, I only get cold air blowing.
#91 of 144 Fan Speed
Dec 29, 2010 (10:16 pm)
The fan on my Impala 2000 is not working correctly. I've been loosing speeds one by one. If I put the knob on 1 or 2 nothing happens - minimum speed is now 3 so its either off or roaring which is annoying. Now 3 seems to be failing.
Anyone know if this is switch or the fan motor?
