L322 Heater controls not working

Good morning,

I have a problem with my 2009 Land Rover Range Rover L322 3.6TDV8 - the heater control panel is completely dead despite power being registered at the loom behind the panel.

I have tried checking all the fuses & replacing the panel with a known good second hand panel.

The rear heated seats are working so am ruling out the heater ECU on this basis - is this correct?

Any ideas appreciated as I'm a bit stuck!

Many thanks,
Daniel

Hi there, so if you have a live to the panel, have you checked for an earth also. Try a continuity check for earth and or supply another earth and live.
