I've got a '97 Seville SLS with the dual climate controls. When the
climate tempurature is set close to the outside temp, the driver's side
cooling unit sometimes flakes out and blows hot air. It's sporadic, and
I just got back from having it at the dealership for a day and they
cannot find the problem. It won't do it for them, nor the other mechanic
who's looked at it. There's a CD player in the trunk that acts up
sometimes..could that possibly be causing electrical weirdness and the
heat/air conditioning switching that I see??
