Air conditioner only worked on first setting. Mechanic told me that the door that controls where the air went was not working and would cost $500 to $600 for repairs. Seemed to work fine with heat, but not with air. Mechanic stated the door was a small plastic piece, but he would have to remove the entire dashboard to get to it. No discernible reason for this malfunction.
