The dome light in my 2001 quad cab quit working. I assumed it would be a simple matter to remove or open the fixture to check for the presence of voltage and or replace the bulb. When I attempted removal it felt like I was going to break something like a plastic retaining clip or something and I really don't want my dome light dangling by the wires as I'm heading out on a loooong trip this week. Has anybody else here had their dome light apart and if so what is the trick? Before you ask yes the cargo lights and front courtesy lights are operative so I don't believe I have a fuse problem. Thanks in advance; Steve.
