You must first remove the trunk door facia. (This is the part with the "Pontiac" lights in it.) Then you can get to the bulb to replace it.
in the trunk or under your back seat
One that fits.......
you go to the dealership
it seem to be the trunk plastic is broke and I have brought the the part and wont to fix it
Old age and vibration, I'd guess. All of mine were out too. The PONTIAC on the trunk lid wouldn't light up. I replaced the bulbs and now it does. For what it's worth, it's Way Cool when the PONTIAC does light up!
beside the drivers seat...on the floor
It's should be on the left hinge. (Small plastic end piece)
Trunk light switch is part of the trunk light socket assembly...
On a 1998 Pontiac Sunfire, the tag light is located above the rear license plate. It is typically housed within the rear trunk lid or panel, illuminating the license plate for visibility at night. To access the bulb for replacement, you may need to remove any covering or panel that shields it.
If you're asking about the piece that lights up PONTIAC across the trunk lid, it comes off from inside the trunk. There are half a dozen or so, screws. I had to pull mine off to get at those lamps that make the PONTIAC logo light up. Normally, you can get at those lamps, but mine were stuck in there pretty tight.
I'm guessing that you're referring to the lamps that light up the PONTIAC name across the center of the trunk lid. You access those lamps from the inside of the trunk lid IE: the back of the PONTIAC name. Mine were pretty stuck in place, so I ended up removing that entire rear light assembly. It comes out with about 6 screws. That gives you more access to the connectors.
