Chevrolet Impala Climate Control/AC/Heater



  • strosestrose Posts: 1
    I'm having the same problem with my '08 Impala.

    And for months now I've been getting outside fumes in even when the a/c is set to RECIRCULATE. Could this be due to the same problem? There are less than 39,000 miles on the car.
  • My 2008 Impapa 21000 miles Has no heat when the vehicle idles also had to replace 4 tires due to uneven wear . Vehicle has been serviced on a regular basis.
  • Bad news, this was a temp fix. I had to replace the actuator and now it works just fine. Currently right at $50.00 with tax from the Chevrolet dealer.
  • Thanks for posting this - this is my first summer in my 2008 Impala - just bought it in Dec 2012. Now I am constantly fiddling with these controls trying to get the air temperature to a comfortable setting. And it seemed to me that even though the A/C light wasnt lit - that it was still on....b/c it was! I am in Virginia so leaving the outside air open isnt an option b/c even though it might not be real hot outside - the air is still moist from the humidity, so I have / want to keep the recirculating on. But instead of just recirculating the cool air already in the car- the A/C is still on, wasting the gas..

    I brought this up with the dealer and Chevy Motor Division. There are a lot of people out there driving their cars with the A/C running and the weather does not call for it. The only solution you have is to put the blower control knob to off & turn the recirculating air switch to on. The A/C will not kick on. If you move the blower knob to a higher position the A/C will kick on, the lite will stay off & you cannot shut the A/C off.
  • my 2006 Chevy Impala won't cool on outside air but does on inside recirculated air. It has never worked right. Took it in to the dealer for service when it was still under warranty and was told there was nothing wrong with it and was charged for the service check. It didn't work right then and is worse now. It use to eventually cool down some with outside air but won't at all now. I need to sell it as my husband can no longer drive. It has less than 46,000 miles on it and I can't sell it the way it is. Any ideas what might be wrong, I know if I take it into the dealer it will be a costly bill.
  • I have a 2008 Chevy Impala LTZ with Dual heat and air controls. The drivers side heater will only blow cold air. I took it to the Chevy dealer and he said it will cost $715.00 to fix. Is this possible? Reading some of the post they are saying $50 part and an hour to fix....
  • Good afternoon needsimplefix,

    As customer service agents, we do rely upon the dealership's diagnosis on a vehicle, but we are willing to check into this further. If you would like for us to to find out more about the diagnosis, please send us an email at with more details (including your name and Edmunds username, phone and address, the last 8 digits of your VIN and current mileage, and the name of your dealership).

    All the best,

  • OK... my heat was working yesterday, this morning, nothing. I would get a little bit of heat, then it would turn cold. When I would slow down, the temperature gauge would start to rise, then it would come back down. When I was full speed on the freeway, it would fluctuate a bit, and I'd feel the heat come and go, slow down to street roads and it is going from 1/3 to 3/4 and back. I'm thinking it's the thermostat, any thoughts?

    OK... found a leak, not sure what it is, pump maybe. If I can get a picture posted I will.
  • Hi, my 2006 impala is doing the same thing yours was doing in 2008. How were you able to resolve your problem? Thanks!
  • Hi Kyle. Never got it resolved. Chevrolet said that was normal.
  • I brought this new. The switch from floor to defrost stops working. I get no air in the summer to no heat in winter.
    Now for the forth time and $489.52 . I am not happy only 23k. I know I will have it back in
    because they only calibrated it. Last Chevy in this household. :(

    This just happened to me this morning. I've got a 2005 Imapala LS. I warmed my car up to find it was blowing cold air and the temp guage was near 3/4. When I would give it gas the temp guage would drop to normal (about 1/3) and I would get hot air. When I would coast, the guage would rise and the air would get colder. I bought this car used from a family friend who is a dealer. The car was garage kept, driven a handful of miles a week and meticulously maintained. Really surprised to have this happen.

    Anyone find out what exactly makes this happen? Do I need to get it into my mechanic ASAP? :confuse:

    Check your coolant level. Sounds like there may be a problem with your water pump as well. You need to get this checked out. You do not want to have your car overheat...

    Same thing was happening for me. It was the water pump.
  • Hello, I work as a public safety mechanic for municipality. We are not fans of Chevrolet. We have been having heating problems with Chevrolet Impalas. It seems to only occur in cars with 3.9l engines with the Active Fuel Management system. At idle the car will lose heat. As long as the car is moving, the heat is fine. If the car sits at idle, even at a traffic light, it blows cold. We purchased many of these vehicles used, with low miles. The coolant level is fine, not a problem with the thermostat, no leaks in the system. Although, I have not checked the ECT sensor with the scan tool, according to the dash, the temp holds pretty constant. Chevrolet cannot tell us why this is happening. This is not happening with just one car. It is EVERY car with a 3.9l w/Active Fuel Management. Has anybody else run into this? Has anybody found a solution to the problem?
  • I need some assistance on the blower motor for a 2010 chevy impala. The blower motor continuously stays on, even with the vehicle off. I removed all fan buses, however it did nothing. Any guidance would be greatly appreciated.

    The AC control would intermittently work and not at the setting indicated. Sometimes it would come on, sometimes not. When the blower would come on, it would not be at the speed indicated. Then the blower would not turn off, even with the key removed from the ignition. It finally stayed on long enough to drain my brand new battery. I was told it was the blower control module AND the HVAC Control. One shorted out the other. Is the dealer trying to scam me?
  • My AC works but if I have it on the max setting I get an unbearably loud clicking noise so I just move it down a notch below max setting and the clicking stops.

  • I have the same issue with my 2008 chevy impala

    I have an 05 Chevy Impala and the A/C works great but when heat is engaged I only get heat from the passenger side of the vehicle, regardless of the setting on the dual climate control...Others have the same or similar problem but no one can pinpoint the solution. Can someone please help???

    have u tried the air flow actuator, my 2005 impala doing same thing im gonna try this first
  • i have a 2005 impala, and the heater is not blowing hot air, I have checked coolant levels, and they are fine, bled coolant lines, not sure exactly how to back flush the system, or what I'm looking for on the actuators, I'm a single father of four and can't afford to put it in the shop. Please help.
