Need to know how to replace trunk light not working?

The switch is located in the latch of the trunk, make sure the wire connector to the switch is not pulled loose or otherwise damaged.

there is a tail lamp failure sensor located in the trunk on the drivers side around the gas door area..take apart and lok on both sides of the board and see if there are any burnt spots...if any part of the board is burnt replace the sensor and all the bulbs in the rear and if there is any kind of add on trailor harness remove it.....also in the trunk on the left side trunk hindge there is a harness that runs to the sensor and the tail lights......look good at the harness where it comes from the inside of the car to the trunk at the bottom back side of the hindge there is a place where 2 harness come together and where it will bend every time you open and close the trunk........look good for any broken wires cause this is a common problem with this year and model......let me and fixya know if i was of any help to you and a thumbs up and a comment would be greatly appreciated....if you need anymore advice let me know......good luck and have a blessed day.........

Open the truck & remove philips head screw that is located to the left of the tail light housing in the trunk lid weatherstripping housing area. Next unscrew the trunk lining screw to fold back the trunk lining to get at the two plastic wing nuts that hold the light housing.

Unscrew these two wing nuts and slide the housing out, then remove the bulbs and replace. Bulbs come out similarly to how you'd replace the front headlight bulbs (unplug, twist counter-clockwise to unlock and remove old bulb, replace with new bulb and turn clockwise to lock, plug back in).

For your first problem I would suggest taking a test light and double checking the fuses I would always recommend doing that because I have worked on numerous vehicles where the fuses were pulled and not replaced firmly and not making contact (just a good thorough habit to get into) if your fuse has power check for power on either your dome or personal reading lamps they are both on the same circuit. If you have power then replace the bulbs if not you will need to check for power between the lights to your illuminator/interior light switch this should isolate if you have a defective circuit ie:shorted,cut,loose wire connection which would need to be repaired. Your second problem the trunk open indicator showing it is still on when closed: open your trunk with the key on have someone push the trunk lid jamb switch several times to check for proper function if it still shows to be opened then it will need to be replaced if it goes on and off as it should then you should check your weather strip/struts and all components & function of trunk to ensure it is properly closing and not out of proper alignment. Hope this helps and if you have any more questions let me know.

If it's one of the lower ones... go in through the trunk, look to see if carpeting or a cover needs to be removed, or peeled back, usually the sockets twists (turns) to be removed, then the bulb will be exposed. An 1157 bulb needs to be pushed in slightly and turned to remove, (Counter clockwise) A 3157 bulb pulles straight out. Also note that some vehicles still need the exterior lens to be taken off, but I do believe yours is sealed!

with a 12 volt test light check fuse ( #22 not entirely sure, or in the 20's ) 20A fuse blown. controls both trunk release and fuel door. Hope this helps.

did it quit making the noise when you lightly push down on the trunk? most people slam these trunks and your not suppose to you are only to put light pressure on them and they pull it closed theirself.. you might check your relays under the hood and look in the box lid to see which one it is.. if this is not the problem you might have to replace the motor to the latch .. you might check with a test light to see if there is power to the motor first though .. thanks and holler if you have more Jerry .

MY 06 Impala tunk would not open using my key fob, or the trunk button on my car . IF you own this vehicle you know that there is no manual keyhole on the trunk. I had to remove my back seat . It is held on by two bolts. In the trunk on the trunk lid is an emergency release handle. Once the trunk is open you need to remove the lock mechanism. Take a test lightand check the wire harness. If you are getting power to the harness and the lock still does not work, you need to replace it. GM wanted 189 for a new lock mechanism, i went to a auto scrap yard. they didnt have an 06 impala, but they did have an 06 malibu. they use the same lock system.the wire connectors for the harnesses look different but it fits fine. the only drawback is my convenience light in my trunk does not work when the trunk is open. only cost 15 bucks for the part.

Clean the area around the light and on the body of the car where the light fits in the area for the gasket.. You can lightly grease the gasket on both sides before fitting the gasket and appling the light cluster to the body work. Do not over tighten the fixing nuts/bolts.

On very serious cases I have used silicon sealant in place of the grease. Be careful if you go this route because you may need to replace the light clusters and will need to be careful when taking them off not to do any damage to the paint work.

This solution has worked on Ford, Vauxhall and VW in the past. I know it is a pain having a boot full of water. I hope this information is helpful to you.

open the trunk... on the other side of the light, in the trunk, fold down the fabric, unscrew the light housing and pull it out... you should be able to get to the light from there.  If you can't get it I think autozone will install it for you.
