Dad and I were tinkering the other evening, got to talking as to why the dome light never worked when the doors were open. He said as long as he could remember, it didn't work.
Turns out the fuse was gone.
We put a fuse in, and now it works and that annoying door buzzer does too! He turned and looked at me and said "ha, there's the reason why it didn't work anymore". I laughed.
Thought I'd share.
