I need to replace plastic on the tail light of a 1990 pulsar hatch and cant see how to get the old one out, there seems to only be one screw holding it?

You need to remove the vinel panel from the rear hatch.Peal back plastic from access hole. Remove 4 hexnuts that hold the tag light , hatch switch and window controller assemply in place.Pop loose assembly from hatch, remove 2pl head screws that hold opner switch to assembly didconect wireing conector. install new switch.

which brake light? if it is in the sides, drop the tailgate/back door and remove the screws holding the tail light assembly in and then it should just pop out. If it is a 3rd brake light, 2 screws hold the cover in and remove those and carefully pry the plastic cover out and gently pull on the bulb

Open hatch, on inside there will be two plastic clips that go into the side of the tail light, remove the center of the plastic clips, they will pop out, remove the rest of the remaining clip, once you have the plastic clips out, tail light will come off, no screw's holding tail light, just those two plastic clips.

OPEN TRUNK LOOK WHERE TAILS LOCATED LOOK FOR LARGE PLASTIC WING NUTS.REMOVE THEM PULL TRUNK LINER AWAY ENOUGH TO REMOVE THE OTHER PLASTIC WING NUTS HOLD THE TAIL LIGHT COVER.WHEN YOU REMOVE ALL THE PLASTIC WING NUTS THE TAIL LIGHT COVER WILL COME OUT ENOUGH FOR YOU TO REMOVE THE BULB.

left tail light is not real. Have a look under boomper. Ther is no kable. Is only one tile light in most of cars.

First you need to lift the hatch. There are two screws under plastic caps. Remove the caps and you will be able to unscrew these screws. Carefully using a flat screw driver to pry out the tail light assembly. It have to plastic pin that attached to the car body. do not break the pin. After you pry out the tail light assembly, you will be able to replace the light bulb. Replace everything in a reverse order.

You have to unscrew one or two screws (don't remember) to remove the whole light assembly (need the hatch or trunk open to access screws). The solution is work from outside the car not inside.

open hatch, look for two screws, remove , push tail light gently back and forth to release from clips pull light assembly out , twist bulb socket to remove from housing, replace bulb.

I did it!!! To change the left brakelight, you open the hatch and remove the two screws on the right side of the light assembly. Then remove the cubby hole inside the left side of the hatch. Inside you will see 3 hex nuts. You only have to remove the one in the center (closest to you) not the ones down and inside. Once you remove that nut, pull the light assembly off (from the outside). There is a plug that will be holding it on. I carefully **** a straight screwdriver in the narrow side just to get it to move out a little, then you grab the whole thing and pull it out, you may have to wiggle it some. It seems like it will break, but it won't. It's just a metal thing sticking into a plug. The whole assembly will pull out (not too hard so you don't break any wires or connectors) then you follow the instructions to replace the bulb. Once the bulb is replaced, you simply line up the metal thing as you push the assembly back on. You might have to smack (open bare handed please) to get it back in. Replace all screws and stuff and that's it!

Look inside behind the light and see if there is an access cover, if not you will have to remove the tail lamp to replace the bulb. If you open the rear hatch and look at the lamp you should see a couple of screws that hold the lamp to the car. Remove these and pull the light out.
