My fan speeds remain constant, but sometimes the air will blow less cool for 30 second - 1 minute. I read that this is caused by the type of compressor in the car.

Feel free to send us a private message with your full contact information, VIN, current mileage, and dealership name. I look forward to hearing from you!
