Why did the passenger side of the dual climate control on my Buick Lucerne only start blowing cold air? Have no heat on that side, just air conditioning works
May b a blend door issue.. If its electronic unit then maybe a actuator gone bad If controlled by vacuum then a broken/loose hose Does that side change from different settings(dash/floor/defrost even)= blend door issue usually
