Assuming the proper steps are being used, there have been people that had a problem with the button contacts getting worn. Some believe the problem starts when the button is pushed down hard over a period of time and the contacts do not make contact anymore. It will probably get worse the harder you push until one day, it just doesn't work anymore. I think the buttons (one side of the contacts) are an integral part of the dash assembly. I have never taken the assembly out myself. Since the time I read about the possible problem, I have only tried to push down as lightly as possible to make contact in order to possibly prolong the problem that may arise in the future.
