Alright, so I inherited an 81 W150 from my grandfather after his passing. I pulled the instrument cluster out to replace the bulbs because they weren’t doing to great after 40 years. After putting it all back together, the brights indicator doesn’t work, and the brights won’t come on. The low beams and all the other lamps/ turn signals work, but when I step on the dimmer switch the brights don’t come on. Any ideas on what the problem could be? I should add that the brights worked a couple nights ago, and the high beam indicator would come on but was extremely dim.
