1999 Dodge Neon rear license Plate bulb

The headlight fuses are in the cabin. Not sure where, but start looking under the dash on driver sude. The box may have a cover.
else, look for a panel cover in the pillars. The licence plate light is probably burned out, as it runs on the same circuit as the running lights.

Front and rear don't work, or just rear? Have you checked for voltage in the bulb sockets?

If it is not possible to take the lens off from the outside. (this is the normal way on most cars) Open the tailgate and remove the whole interior panel. Its not as hard as it sounds. This should allow access.

That makes sense since the rear taillights and license plate lamps come from the same power source, which is different that the ones for the backup and brake lights. Here are two diagrams that show the electrical path for the lights from the battery/fusebox all the way to the lamps. Hope this helps!

If the lens, or lenses, don't have screws then in all probability you'll need to access the lamps from inside the trunk. You'll probably have to remove some kind of trunk liner or maybe pop off some access covers to get to the bulb sockets. You'll need to remove the bulb socket(s) which may have some kind of plastic "lock" you have to press ...just take your time and look at the socket. Then again they may just twist out.

Hello: Remove the license plate, then remove the screws on the chrome piece behind the license plate and the you can access the bulbs.

Hello, remove the rear license plate, remove the housing where the license plate was mounted, now you can see how to replace the bulbs.

how to replace the Dodge durango 2004 number plate light

looking at your schematics and , you say tail lights don't work , you didn't mention if front parking lights and license plate lights are working , they all come from the same source , a black /yellow wire , a good clue if front work and rear don't , please advise .if fronts work then you have a open circuit somewhere between junction S118 (near breakout for left headlamp) and rear sockets.
