Why doesn't my cars heat work properly ?
three weeks ago my passenger side vents only shot out cold air while my drivers side was fine. After a few days my drivers side air began to be cold. I went to get it flushed about two weeks. After the flush the heat was working great! Up until yesterday that is. Yesterday I noticed that the passenger side vents have cold air while the drivers side is hot. I have the dial turned all the way up on the heat. Any idea on what it could be? Should I get it flushed again or is it something else?
