Cant get parking light fixture off to replace bulb.

First make sure there is no power to the fixture or this will shock you. Then use a pair of needle nose pliers to grab the remaining metal part of the bulb that’s stuck in the fixture. Make sure not to grab the fixture itself.

often have an access panel you can remove to acces the bulbs from the rear door on the inside, if not you must remove the light fixture from the outside either my removing a screw holding the light housing or carefully pulling the plastic lens out, generally there is a or multiple screws holding the light fixture in place.

The side marker light must be removed in order to get at the turn signal light.
There are two screws holding the side marker light which is situated above the turn signal.
Open the hood.
Remove the phillips head screw at the top of the side marker light.
Using a long #2 Phillips screwdriver, remove the screw on the outside of the side marker light. This can be seen by looking between the lower side of the side marker light and the top side of the turn signal.
The side marker can be moved.
The turn signal has one screw on the top of the fixture that must be removed.
Slide out the turn signal fixture. There is a small feature on the lower front corner of the turn signal fixture that you must note to properly reinstall the turn signal.
In order to get to the bulb, rotate the bulb socket 1/4 turn CW or CCW. The bulb socket is loose.
The bulb is simply pressed into the socket.
Not sure of the type, but it can be found at your locale auto parts store.
The bulb is used in several places on the 1994 GC, so get apacket with two, if possible.
Assembly in reverse. Be careful not to overtighten the screws as they are replaced

If you are talking about the turn signal, there is a second screw located between the bottom of the side marker light and the top of the turn signal light. You will need a long #2 screwdriver to get at the screw. You also may need to pry apart the two light fixtures to see the screw.
There is one screw holding the turn signal in place.

Pay attention to the little protrusion at the front side of the turn signal fixture. It needs to be placed behind the matching fixture near the side of the headlight.

lift the tailgate

unscrew the 2 hex screws with a socket wrench.

the entire back light fixture will now be able to be poped out. Pull slowly and firm on the fixture it will pop free.

Behind the fixture you will see the wires leading to your light bulb turn a quarter turn to loosen and remove the socket. change the bulb and repeat the steps backwards to replace the light.

open tailgate and look for 2 screws in between light fixture and tailgate. remove two screws and take entire light assembly out to access light-bulbs.

look in between the marker and headlights its a screw there screw it out

heres how you go about removing the headlight and replacing bulbs:

you will need a 7-point star screwdriver (6+ inches)

1) unscrew the two screws on the tabs above the headlight fixture (if one is missing its not a big deal)

2) unscrew the screw on the bottom of the light fixture. It will be on the inside bottom of the light (towards the grille).

3) For the driver side: unscrew the screw that is slightly infront of the power steering reservoir (if its stuck you may need a wrench to get some movement). This screw only needs to be loosened, don't unscrew it all the way.

For the passenger side: unhook the left part of the air filter (don't worry, it pops in and out easily) there should be a screw towards the hole for the air filter on the upper left of the light, loosen it.

4) Slide the headlight fixture out of the car and undo the little metal clips over the covers. take off which ever cover holds the old bulb and replace it witht he new one. BE CAREFUL! DON;T TOUCH THE BULB WITH YOUR FINGERS, THE OIL MAY CAUSE THEM TO EXPLODE

And on the off chance you make the same mistake as me and drop the screwdrier into the engine block, park your car up on a curb and get it from below.

hope this helps!

You really have just five choices here:

1. eBay. That's where I found mine. It took an age, but I eventually found one but it was pricey.
2. Post classified wanted ad on sites such as www.300zxclub.com.
3. Local pick-and-pull car dismantlers, but phone ahead to save you an unnecessary trip. Z32s are not that common in wrecking yards.
4. Online parts companies, such as RockAuto, not as expensive as the dealer.
5. Pay retail from your local Nissan dealer.

Best of luck in finding your part.
