Troubleshoot Air Conditioning
Start the engine and let it to run for a few minutes to allow the air to cool. Double check the controls to make sure the correct buttons are selected.
Check the coolant levels if the air seems to run fine but does not get cool. The coolant reservoir is under the hood at the very front of the vehicle in a white plastic container with a cap.
