Hi,

I have Tahoe 2009 2WD.
I first had a problem with AC grills not working appropriately. The air comes out from front defroster after I switched on fan on every car restart & then I had to move mode control dial forward and backward to get the airflow from Dashboard vents.

Recently I did the interior deep clean of car. They remove the battery wires in order to move the seats.
After they set the wires back to the battery and started the car, the air directly came from dashboard vents surprisingly since that day but I faced a problem;

WHENEVER I SWITCH ON THE AIR RECIRCULATION BUTTON (with the Fan on), THE AC COMPRESSOR STARTS WORKING WITHOUT THE NEED TO SWITCH ON AC BUTTON.

Any help appreciated.

Thanks
