I ordered a new switch for the upper glove box and the light bulb still doesn’t work on my 2011 Ram 2500 mega . Any idea why ? I also bought a LED bulb and I’m wondering if there is a blown fuse .

 

I do not have a wiring schematic but fuses are mostly a thing of the past besides on high amp dedicated circuits with the incoming of TIPM modules, computers ect.

Did the LED work when it was initially installed? If not did you try flipping directions? Correct bulb/ votage?
