DeVille Dual Climate Control Problem


CruellaDeVille

Recommended Posts

I have a '99 Deville with the dual climate zones. Just resently it starting blowing warm air out of the passenger vents, but only on occassion. The controller is turned off on the passenger side. Even it I turn it on and put it to cold it still blows warm air. Any ideas as to what might be wrong? Thanks!
