Both of my low beam headlights broke at the same time. The high beam headlights work when selected. So I'm thinking electrical, not a blown bulb. Removed bulbs they look fine. Checked out fuses they are fine #19 and #20 15 amp. When I select headlights, the instrument cluster works, sidemarker and rear tail lights all work, but no headlights. I called the volvo dealership for a relay and they gave me a 5 prong headlight relay marked K. I do not have fog lights or rear fog lights. The only other thing is the actual switch but how does everthing else work. rrrrr... Any help would be grealty appreciated.
