HVAC prbs

My HVAC controls (the green lights in all 4 circles don't light up, so there is no function at all) would not work about 10% of the time I start up the car. So the dealer diagnosed the prb and supposedly it was a faulty control unit, which was subsequently replaced. However, the prb still occurs: not sure if you guys have any ideas what it could be? It is very weird because it still works but sometimes it doesn't.
