Hi,

Just picked up a 2018 XC90 T6 and finding a few problems....one of them being that the second and Third Row ceiling (dome / reading) lights are not working. I checked the fue 28 under glovebox and was blown. Replaced with new one and immediately blew it again. There must be a short somewhere but not sure where to start. Thinking maybe a sunroof leak as I noticed some water come in from the front mirror, but maybe I didnt close the sunroof well, because the drains work great. The front dome lights are working well as well as the rear cargo area lower side lights. Any suggestions where/how to troubleshoot??
