Hi!! this is a common problem for this type of vehicles, the fix is simple, replace the LEFT Air Temp. Actuator. THIS IS HOW THE LEFT AIR TEMP. ACTUATOR OR ALSO CALLED BLEND DOOR ACTUATOR $35.99. IF YOU HAVE IT DONE BY A SHOP, It costs $230.00 for labor and the part. On my 2005 Impala the - 9d16692.jpg

  1. Disconnect the negative battery cable.
  2. Remove the instrument cluster trim plate, as follows:
    1. Remove the retaining screws from the instrument panel accessory trim plate.
    2. Pull the instrument panel accessory trim plate rearward to release the retainers.
    3. Rotate the trim panel rearward and up to release the tabs at the top edge.

  3. Remove the retaining screws from the heater & A/C control panels. Pull the control panel forward and unsnap the retainers at the ends. Detach the electrical connector(s) from the back of the panel. Some models may have a vacuum line connection that must also be removed.
  4. Installation is the reverse of the removal process. Use care to make sure the retaining clips are properly seated and all screws are in place. This helps avoid rattles and squeaks later.

I have a 2005 impala. my rear defrost does not work. i dont seem to be getting power to the grid. the grid looks good, and the connections to it seem fine. i cant locate the defrost breaker or relay. all...


to check it take a multimeter and place it on each connection of the rear defrost to make sure you don't have a break somewhere in the defroster

My 2005 chevy impala blows heat on the passenger side and cold air on the drivers side. Please help! I have tried disconnecting the power fuse for ten minutes to recalibrate and nothing.


I have the same issue with my 2005 chevrolet impala. I took it to the shop and its the dual module control out on the driver side which will cost anywhere from $300.00 to $500.00 to get fixed.

2005 Chevy Impala driver's side heat blows cold, but works on passenger side. Was told a vent is probably not opening to allow for the heat to get to the driver's side? Where can I locate this vent?


First....buy a drivers side air flow actuator at a auto parts place for dual zone heating/cooling.
(NAPA etc will have it.....or the dealer)
Open the glove compartment.....all the way....you may have to take the screws out at the bottom......look in at the heater assembly....look over to the left....you will see the two air flow actuators.
Look at the part you have and match it to the part on the heater assembly.
The actuator that is closest to the engine is the drivers side control.
Replace it.
Try your controls and check for heat and cooling on both sides.
The stepper motor in these actuators goes bad on quite a few...but over look that.....you have a great car,good for many miles of trouble free driving.

I drive a 2005 chevy impala.. everytime i turn on the heater and the driver's side blows out cold air and the passenger side blows out heat.. can you please tell me what is wrong


Do you have separate drivers side and passenger heat controls?
If you do have this system,the common problem is the control unit s on the heater/a/c assembly. Can you adjust heat and cooling on one side?
Then the other side control unit is most likely bad.

No heat in 2005 Chevy Impala,,,,air worked fine all summer, blower works, just no heat on drivers side and minimal heat on passenger side....this car is nothing but problems


GM Yuck! I'm surprised you haven't had a bad anti-theft system yet!

No heat is due to a bad heater core. Or the flap that directs the air inside the venting gets stuck in one position and you have to tear apart the whole dang thing to get to it.
