HVAC Control panel has no power on 2000 lincoln navigator?

Heat and AC control panel has no power on Lincoln navigator.'
In this cases the first thing to be checked is fuse.

The Control panel is powered up by the #2 fuse and the #22 fuse in the interior fuse panel and if they check ok then you need to remove the controller and check to see if you have key on voltage at the white/violet wire and the red/white power wires at the connector on the controller. If you do and the controller is still blank then it has likely failed.
