Chevy 2010 Impala - fan/defrost delay

Asked by Karen Nov 16, 2021 at 04:08 PM about the 2010 Chevrolet Impala

Question type: Maintenance & Repair

Round wheel for fan/AC/heat/defrost should enable all functions to work in
seconds, but no sound and nothing happens. Other times it works properly;
most times there is a long delay, and it might work, and then after 10 min
whatever I have the wheel turned to - defrost for example it comes on strong.
