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. This may seem simplistic, but human error could be to blame.
Check for proper levels of coolant. The reservoir is located at the very front of the vehicle in a white plastic jug. Remove the cap of the reservoir and shine a flashlight into it. Look at the side of the container to make sure the level of coolant is between the full and low lines.
