if it's still unfitted to the heater box and unplugged from the HEVAC ecu check out the pin connections in the plug using 'Rave' and connect power source to the relevant pins watching for the correct movement, reversing pos and neg sends it back the other way, if that works and you have an ohm meter, check the resistance on the pins from the variable pot', one way then the other, they should be the same, in the centre they won't be, if the positional resistances prove ok then the ecu or it's socket could be suspect.

cheers John
