Do check for power at the grid and make sure that the connections are clean. Many times these things are just dirty connections.
I think the light assembly screws out from the inside of the trunk.
Should have an access panel inside trunk
what year is the car fisrt of all? If it is a 1989 it is located on the driver side near the light dimmer switch. There are two thumbscrews you have to remove to access the fuse box, on the inside of the panel there is the diagram.

As most vehicle defogger controls operate in a similar manner, and as I'm not familiar with your make and model, this answer will be generic in nature. Rear defoggers generally draw a fairly large amount of current, and therefore that current does not pass through the cabin control switch. That switch controls a special type of relay [a time delay relay]. When you press the switch to turn the defogger on, an electrical pulse is sent to the time delay relay which closes, passing electrical current to the defogger grid. Within the relay is a timing circuit which, after a finite period of time, is supposed to release, and open the relay switch contacts, turning off the current to the defogger. From your question, I suspect that your defogger relay has FAILED IN THE ON POSITION. Usually, this failure is fatal to the relay, which must be replaced. I have a Buick Century wagon 1996, and I ran into this problem. Have you noticed if the defogger switch lights up when you hit the brake? If so, you have a bad connection somewhere. The center brake light is on the same circuit as the defogger, so you may notice that the center brake light does not light up when you hit the brake. So if this is what's happenning to you, you either have a burned out center brake light, or the defogger terminals in the rear window aren't making a good clean connection. They are located on either side of the window near the top. What I did to fix this was to solder a small piece of metal to the terminal that was not connecting and it was thick enough to make the connection. So the center brake light works, and the defogger now works exactly as it should. Hope this helps.
The socket size for the trunk tail light on a 2001 Buick LeSabre is 7mm. Bulbs can be purchased at most local automotive repair stores.
I have Park Ave. It may be the same. I removed the headlight assy and then had adequate access to change the side bulbs. This assy can be removed by removing two thumbscrews. Hope this is the same for you.
This is straight from the owners manual, turn key to "on" position but not "run" position. Open glove box and on the left side of glove is the reset button,as well as the truck on/off button.Press and hold the oil reset button for 5-6 seconds. this will reset the change oil indicator for approx 3000 miles. On my 1997 LeSabre, there is a switch in the glove box that permits one to reset (turn-off) the change oil light by holding it down about 3 to 5 seconds.
The Peugeot 206 is a subcompact car. One has to remove the full light to change indicator bulb. A spanner can be used to remove the light cluster. Break the spanner off, and rebuild.

On my 2002 I turn key to ON, but don't start, pump gas pedal 3 times, turn off key. Mark
