Hi Chris .

if i turn the controls to the screen or foot, the air is cold, but once change control to face or face/foot, the middle vent blows warm and the two outer vents (passenger and driver) blow cold

Hi Chris .

okay just checked the system you have and is an automatic system .

What you need to do is have the system hooked up to a scan tool to check for malfunction codes , you may have a B1512 or B1514 code which is the air flow control actuator .
you may only need the system resetting with the scan tool , i have seen this with the system having warm air on one side and cold on the other side ,
Once the airflow actuator is reset then the flow should be back to normal .
Also possible one of the flow control flaps has got stuck and will not fully return .

Have you noticed that the A/C or rec light flashing when the system is running .

Customer: replied 4 years ago.

yes, i have noticed that the ac light flashes all the time when the ac is on or off

Customer: replied 4 years ago.

if a flap has gotten stuck, how will i be able to have that fixed?


Chris this is a timely operation of basically removing the dash from the car to get at the flap controls .

Hi Chris .

Okay this is good as this means the A/C management system has seen the problem and stored a code to let us know that there is a malfunction in the system .

Now you need to know what the code is ,
Dealer scan tool to check for codes may need a repair or just resetting .

Ring a few local garage and see if they can help you ,

Not 100% sure but AutoZone may be able to read you the code FREE with there scan tool.if they can then post me the codes if needed for further assistance .
If not then you will need a dealer scan tool to get you the malfunction codes .

One thing i would try first is to disconnect the battery and connect the two cables together for a few seconds then reconnect and retest the A/C .

Need further assistance then please get back to me with the reply box and not the poor or bad service button .

u mean the two terminal wires?

Customer: replied 4 years ago.

if i bring vehicle to dealer and they run the scan and they get a code, would the code tell them wat is the exact problem?

Hi .

Chris the two battery terminal cables touch together ,remove the neg cable first then the pos cable refit in reverse .

If they hook up the scan tool and find codes then yes this will lead them in to the right direction where the problem is , and as said you may only have to have the actuators reset which they can do with there scan tool .
