    OK....there is a trouble code in the onbaord diagnostics that is turning on the light.

    Simultaneously press and hold the OFF and WARMER buttons on the climate control panel with the key on until the onboard diagnostics activates. Read off the codes and see what they are. Post back for more info.

    Impossible to say why the light is on without knowing what codes are stored.

    Well evidently you didn't read much because I posted suggestions in your duplicate posting. Hope you get it fixed.
