I Have A 99 Cadillac SLS, The A/c Works Only On The Passenger Side, Driver Side Blows HOT! WHY?
My cadillac driver side blows hot air in the summer, and cold air in the winter. The car has dual climate controls, but you can't just turn on the passenger side, the driver side has to be on at all times. What could possibly be wrong. Please Help Me. Its 100% here and 150% on me if i turn the air on. Once again please HELP ME.
