Air-con Control Unit Options

[Euphoria]

Hey, I've been having problems with the air con unit, the top lights cut out and if you hit the side they come back on, you can also turn them off by hitting the side haha (I've taken both the rear plugs out and put back in again, still the same)

Also the actual air-con won't blow air ocastionally yet every button works and you can hear the vents moving and you can hear the compressor, its just the turning on that doesn't work, when you select it to let the outside air in it works although only on the off position.

Then it will randomly start working again.

So I'm guessing its the control unit that is playing up and am just wondering if anyone else has had similar problems?
