There was no available switch slot open, so the dome light switch was replaced for the new fan switch. Therefore, dome light switch no longer available on dash due to replacement for engine fan switch. After removing the switch the code dome light subbus switch missing will appear on diagnostic link software, but not as an active code. Try at your very own risk : )
