This is caused in most cases by the air temp control blend door actuator being defective.

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

My 2004 Chevy Impala only blows cold air with heat on. The heater would only keep it a little warm the other day but now only seems to be blowing cold air.


Check in the main radiator with the motor cool that the coolant is full as if the coolant is low there will be no heat in the heater. If it is low you need to check for leaks or head gasket problems. If its full check that the temp guage is coming up to its normal position as the thermostat could be faulty. Then make sure that the heater tap is operating corectly.

2008 Impala heat problems


remove the radiator cap and let the car run for 30 minutes to let the air out of the heater coil, these radiator caps on the 2008 Impala will not bleed off, while running notice if air bubbles air slowly rising to the top of the radiator cap, re-install cap and see if this fixes problem, we also purchased a new radiator cap, this fixed my wifes car.

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.
