Our 2000 S80 seems to be having electrical issues. All of a sudden the headlights (both high & low beams) & turn signals stopped working. The fuses are good & Fog lights or running lights seem to be working fine.

Trunk will not open either remote or key.

Going to try replacing fuses, even through they look fine. I had read about desconnecting battery & reconnecting but its in the trunk which we cannot access.

Any ideas?
Thanks in advance.
