Hi Dynomite--
After talking with Marc Haibeck about fixing my A/C head I thought you should change the description and what needs to be done regarding the intermittent A/C switch problem. The problem is apparently not with the rubber gasket behind the buttons but with a connector between the circuit board that is screwed to the button faceplate (and holds the rubber gasket in place). So you don't even have to take the circuit board off the faceplate after all. On the face plate circuit board are a bunch of fine thin contact prongs that when assembled fit into corresponding sockets in the A/C head. An unusual connector if you will. It is these prongs that get dirty and lose contact from repeated button pushing (they move ever so slightly when the buttons are pushed according to Marc. ) On mine I cleaned them as well so everything works. Marc says he has fixed about 30 A/C heads by simply cleaning these connector prongs. --Bob
