Same here, assumed there was no light because mine isn't illuminated at all. I'd love to see a how-to on replacing itWhen I bought my XJ the hvac was not backlit. When I swapped cluster I pulled things apart and notcied that the connector had come out of it's home. Bulb lit up, but it was stuck behind panel. Not to say that others aren't burned out. But, in mine it was apparent people tinkered and fubar'd dash wiring and such for some reason.
