Interior Lights Won't Work
 

I have a 2001 Chevy Blazer. At first I noticed the dome light wasn't working, so I replaced the bulb in that, soon to find that all the lights actually weren't working. I looked in the operators manual and identified the fuse relating to interior lights (12). I did a visual check of the fuse, and it appears to be a good fuse, I even used a spare and that didn't change anything. I tore apart the dash later and pulled out the over ride button (it's in a plastic box) and checked the wiring running from the switch, the fuse box, and around back behind the radio to see if anything had caught fire or had been severed. Still no luck. Recently I did a repair to the glove box compartment where I had to tear out the bulb and weld the 'U' hook that the latch is held to (I broke it). I don't know if anything that I could of possibly done when attempting to put the light bulb back in, could of caused an issue (I still haven't been able to get the bulb back in properly so I have temporarily just left it).

Proof of recent repairs:

Any help is greatly appreciated. I don't really know that much about cars, so explaining it in general terms would also be greatly appreciated.

Never mind, I feel like an idiot. The fuse that handles what the problem was, the curt. lights fuse (#10 I think), which happens to be blown. Now I just have to fix what I messed up on the over ride switch and I'm all good.

Solved.
