My interior lights and trunk light aren’t working and fuse #24 blows as soon as I change it. Where do I start checking to fix this?

 

if its popping immediately there's a short on wht/blu. try removing both bulbs and see if the fuse blows.

 

Is this new behavior, or has it been doing it since you've owned the car?
If the latter, a previous owner probably monkeyed with the wiring. Some people have been known to
tap off the interior lights to add an accessory such as a radar detector. I'd poke around in there to see
if anything looks amiss.
