Ac/heater panel stop working. No light in it?
You need to be a bit more specific. Did the amber temperature/fan speed display stop working or did all functions stop as well? The control units are prone to fail on these cars as is just the display. There is also a control modules that can go bad as well. Repair of the module is not cost-effective option. I would first suggest having the BMW codes scanned and then replace the offending control or module with a used one. Part will be less than $100 plus you and cost for running codes.
Good luck,

You might want to check and see if you can find any inline fuses going directly to the control panel. I had the same problem on a different car. Just in case.....there should be fuses under dash and under hood. Maybe a relay is even out.

Hi it sounds like either the thermostat or the heater matrix, although if there is air in the system then this would also cause this fault. get the thermostat checked first as this could cause more damage if not fixed quickly.
The heater matrix or heater core may be blocked or not circulating the warm air, This is a more expensive job if it will not unblock.
Hope this helps
