heater control panel nothing working

Hello, My 1996 caravans heater control panel is not working at all, I mean any of the controls on the panel, all of the push buttons and the controls, any help, thanks

Update, I checked all fuses and relays, all ok, I remove the control panel and checked for power, I've got power going to the unit, sooo... now im looking for a new climate control panel, which is the only thing it can now be.

Does anything come to life if you wiggle the panel's connector? If yes then look closely at solder connections where the connector is attached to the circuit board. You may see small cracks in the solder. It's a common problem on instrument cluster circuit boards.
