AC vents on passenger side blowing warm air even though control is set at 70. It doesnt feel like heat, it's probably ambient air. All other vents blow cold air.

You will probably need a new RF temperature actuator which is on top of your HVAC box/under dash pad.($400 + at dealership.) I have replaced MANY....They get stuck and dont know where they are...If you want to try and recalibrate them yourself you can remove the HVAC/ECAS fuse in the underhood fuse block for 30 seconds(engine running) and reinstall the fuse and wait(IMPORTANT) 2 minutes...do not operate the a/c controls during this time...(engine still running) ..Then shut off vehicle and wait 30 seconds.. start the engine again and operate the A/C and see what happens....Hope this helps!!

    I can't thank you enough, this did fix the problem. I assume if it does keep reoccuring i will have to change the R F temp. actuator.

    Many thanks again,

HEAT ONLY BLOWING WARM AIR ON PASSENGER SIDE


have someone check the driver's side temperature control doors, in behind the radio. there are two push rods attached to a plastic piece. the connector on one or both of these push rods, become unattached. leaving you with cold air. once that temperature door is closed you get hot air. passenger side still mixes, but not drivers. All or none for heat on Driver's side

Driver's side air blowing warm, won't change


Sounds like there is a crack in the vent that leads to the drivers side, and hot air from the engine is leaking through.

I would try other settings like heat and regular air to see if air is going to this vent. If it does, the flap may be stuck inside that directs the cold air when it is turned on. The vent is moved by a vacuum actuator.
If you have air on one side, that is a good sign. It may be low pressure, but if the air is cold, it is likely the vent stuck shut.

Ac system


take the dash off to see if the vents are connected to the dash. if not, the heat from the engine is blowing through the open hole

Impala has dual climate control. AC blows cold on


with a dual climate control system, it is imperative for a proper refrigerant charge to be maintained. the symptom you describe is a possible indicator of low charge on the system. the ac evaporator core is closest to the right side of vehicle thereby making air feel cooler on that side, on the left side of the vehicle the cooled air has farther to travel and warms up from cabin air before it discharged from the vents. this is the most probable issue for your vehicle...however if the charge is accurate, the issue would be more so in the air temperature doors which is located deep inside the dash...i hope this helps...good luck!
