Climate Control Problem?
My climate control works fine on all vents when set to 16 degrees. But when I just turn the controls up by half a degree to 16.5 the engine sound changes and warm air starts to flow from the footwells while cold air comes from the middle and top vents. Then just this morning warm air blows at 16.5 degrees from the top side vents. This all worked fine until a couple of weeks ago. Any suggestions would be greatly appreciated.
