Question about Chevrolet Impala

1 Answer

Car has dual climate control, however no heat is getting to the drivers side causing defrost issues. There is adequate airflow, but it is all cold even when set at full heat.

Why did the passenger side of the dual climate control on my Buick Lucerne only start blowing cold air? Have no heat on that side, just air conditioning works.


May b a blend door issue..
If its electronic unit then maybe a actuator gone bad
If controlled by vacuum then a broken/loose hose
Does that side change from different settings(dash/floor/defrost even)= blend door issue usually

Passenger side air is cold coming out of dash but the drivers side air is not cold. I need a solution to the problem?


if this has dual climate controls then the drivers side blend door actuator is not working properly. if it is only single climate control then a low freon level can cause the air on the driver's side to be warmer.

2004 gmc 1500 heat is only blowing on passenger side. driver side is blowing cold air.


sounds like you have dual zone climate control in your truck. Most likely the actuator that controls the temp door in the HVAC box

Climate control only blows cold air driver side, i get heat on passenger side however


This sounds like a "dual-zone" issue. Does this car have this feature. If so, probably one of the temperature sensors. Should be located under the glovebox by the passenger leg area.

Driver side air conditioning will not cool


are you not getting any air or hot air???
Here is a laundry list from my memory as to what may be causing causing the problem.
1. Low freon:car will act like this when it needs a freon recharge. Such did not solve my problem, however.
2. Stuck door. There is supposedly a "door" (for want of a better term) inside the heating/cooling system that regulates temperature and/or cabin airflow. The door opens and closes according to the temperature and and dual climate settings selected. If this door gets stuck, it causes hot to blow out drivers side and cool on the passenger side.
3. temperature sensor improperly reset. if the battery gets disconnected and reconnected improperly, it will cause a malfunction in the sensor responible for delivering the proper temp through the a/c system. Disconnect the battery and reconnect with negative terminal first; check all fuses that reference climate control, a/c , heater, etc in manual, remove for 15 seconds, reinsert or replace if necessary.
4. Computer malfunction. The problem may stem from the climate control interface itself (i.e. the thing with all of the temperature knobs and buttons). Replacing this is supposed to fix the problem.

BEFORE TRYING ANY PROCEDURE PLEASE CHECK THE RESPECTIVE PART

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!

A/C Heater problems


the main issue with this is either the thermostat or the climate control switch I do not know if your climate control switch is electronic or manual either way I would start out with the cheapest and go with the thermostat first good luck!

Only cold air on passenger side


I would assume with multiple people having the same problems, there should be a service bulletin on this issue. may want to call dealer with vin # to verify. sounds like a heater control issue under the dash. something i would leave to the experts for repair
