Impala had a bolt in the dome light / brake light circuit. I cleaned the bulkhead connectors and the fuse block. So far so good except I used a fine sandblaster and removed all of the identification on the fuse block:BangHead::BangHead::BangHead: I printed a picture off the internet. It's in the glove box. Thing has five interior lights. The one in the back of the console got too hot at some time. Melted the housing.
