Oldsmobile/Buick Repair: 93 roadmaster, light fuse, light dims

Question
roadmaster blows the park light/ dash light fuse as soon as you plug it in. headlight switch was removed and it still has the problem. cannot find any shorts. can you help?

Answer
Check your owners manual, and see what else is protected by that same fuse.
Then connect a test light across the fuse terminals, rather than a new fuse.
The light will glow brightly.
Then start unhooking all that it controls, including the connector in the back of the instrument cluster.
When the test light dims, you have found the area.
