Recently stepped into the First Gen world with a 93 W150. Dash lights are dim...but ok...radio light is ok...map light is missing and the heater control is dark. Are there bulbs in the heater control or do these not light up on the first gen Rams? Thought I would ask before ripping my dash apart. Also...has anyone made a map light for their trucks? If so what did you use? Thanks for any input.
