Headstrong Climate Controls - '94 LeSabre
Hi guys, first post from a newb...my wife'* Buick has push button climate control that cycles itself counter-clockwise through the functions, including rear defrost in @ 2-3 second intervals. It registers a button push, but immediately resumes cycling until either it decides to cooperate, or, sometimes, when the engine is restarted. Occasionally, it works as advertised all day - maybe two - but goes back to it'* bad habit. Coincidentally, the computer behind the glove box was replaced just before this all started - could that be it? I've been told it could be the blend door actuator or the circuit board behind the control panel...any ideas would be greatly appreciated.
