    I have the exact same problem ! Hot air comes out of the driver side vent by the window, and the lower driver side vent, and cold air out the right side vents. Not all the time, but sometimes.

Hello, Here is a way to ck the codes in the climate control system.
Ignition ON
Temperature selector Left Hi Right Low
Within 20 seconds, press REST and EC simultaneously for more than 5 seconds
The LED in the car flashes and the display di A
Press auto repeatedly until all DTC's are shown. Record all DTC's
Each malfunction (short circuit, open circuit, etc) has a specific DTC
The letter "E" (error) is displayed in the left of the display and the DTC is displayed in the right of the display. By pressing the AUTO button the next DTC stored in memory will be displayed
To erase, This is only possible after all DTC's are read out
Simultaneously press both AUTO buttons for more than 2 seconds
"d" will be displayed on the left side of the display window and "FF" on the right side
The only problems that I can think of that will cause this problem are as follows;
006 right heater core temp
020 right duo valve
I hop this helps. CYA Gator241

Why does 1 side of dash blow hot and the other cold when ac is on with the dual climate control?


Check the actuator motor on the heater it directs the air into the vents. There is probably two of them be sure to check both. The motor makes the vents move and again directs the air where you want. Hope this helps.

My guess is that one of the hose's has a leak and needs to be replaced. A mechanic can run some tests to check if that's the case. Best of luck.

My lesabre blows warm air on driver side cool air on passenger side


If you have dual climate control, you most likely have a low freon level. The evaporator can get cold enough for the passenger side (where the evaporator is located), but not cold enough to transfer cold air to the passenger side. Have it inspected for a leak and the freon level topped off.

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!
