Greetings, first off this is my first time EVER, posting on a forum. So I hope I do this right and that some folks are kind enough to offer up some assistance. The little rectangular AC push-button (next to the 'recirculate' button) will not shut off (or 'pop back out') when depressed. The AC seems to be working OK. However, the only way to turn it on or off is by the 'Fan Speed Knob'. ie: The AC pushbutton switch stays lighted in the 'ON' position and the only way to turn the AC off is by having the 'Fan Speed Switch' in the 'Off' position. A local dealer stated that I'd have to replace the entire climate control cluster/console. Any thoughts on this. Many thanks in advance.
