Is there anyway to replace the light bulb that illuminates the temp setting for the passanger side climate control. Mine has the dual digital displays and you cannot see the pass. one at all at night. I took the whole unit out and took it apart, but I cannot find the bulb that is for that display....anyone else done this...or know of somewhere on the web it might be discussed?

Thanks
