Default License plate lights and trunk light out

I got pulled over last night for both my license plate lights being out. No ticket or anything, he just ran my license and registration and told me to get the lights fixed. Picked up some replacement bulbs on the way home but when I pulled the license plate bulb, I noticed that it looked fine. I replaced it anyway but the new bulb didn't come on. I checked all the fuses in the dash/engine bay but none were blown. Then I remembered that the trunk light was out too so I replaced that as well. Whoever had the car before me had used a 5W bulb instead of a 16W but the 5W bulb looked ok too. I replaced it with the correct bulb anyway and still nothing. All my other lights (headlights, tails, turn signals, brake, interior) are working. What's left? Wiring? Anyone know if the license plate lights and the trunk light are related anywhere specifically? What should I be looking for? Thanks for any info.

Fuse #5 in the dash panel supplies power to the license plate lights and fuse #2 supplies power to the trunk light. The common point for these circuits is connector B99/R3, and it appears to be either under the front passenger seat or possibly the kick panel area. It is a two row, 24 pin connector. Pin 13 (blue/red) ties power to the trunk light and pin 17 (red/yellow) supplies power to the license plate lights. If you don't have a test light probe already to test with I suggest you get one. You could try seperating the connector and reconnecting it to see if that fixes things. Check for signs of corrosion. Chances are the trouble is with that connector. If not, then you need to check things further back towards the lights. Assuming power is getting to those points at least.

If you do have a volt/ohm meter (or can borrow one), something even easier to test (before needing to remove panels) is to see whether all of those bulb sockets are getting +12 or ground. If the problem is lack of ground, that would likely point to locations back in the trunk.

Thanks for the info guys. I doubled check the fuses and they are good. I checked all the connectors under the seat and in the passenger side kick panel and they all appear to be ok. No corrosion or anything there. I'll have to see if I can get a volt this afternoon. I know my dad used to have one so I'll see if I can get ahold of that. At this point I'm guessing there's a problem with a ground or something of the like in the trunk. (Not sure why I didn't think of this sooner, but the driver's side of the trunk leaks a bit. Chances are, water got in contact with a ground and corroded it so now there is a short.)

You can also purchase a test light probe for under 10 dollars if you need to. Check the voltage on the pins of the connector and make sure you have it there at least.

Thanks for all your help, guys. After all of that, it ended up being the most simple thing... I got rear ended last summer and apparently when the rear bumper was replaced the shop didn't reconnect the two connectors that are right inside the back of the trunk. (The panel that goes around the trunk latch that you remove by just unscrewing the two little plastic fasteners.) If I had thought to check there to begin with it could have been fixed in 23 seconds. This also means that the lights have been out for probably 9 months.

Ah well, at least it was something simple, and I learned a bit about the wiring. Thanks again for everyone's suggestions.
