I need to change the rear turn signal bulb on my recently purchased 2007 Buick Lucerne. How do I remove the plastic fasteners that hold the trunk upholstery in place without breaking them?

If that's the only light not working, the bulb probably needs to be replaced. To get the lamp housing out so you can change the bulb, open the trunk and pull back the liner on the left rear side - there are usually a couple of plastic fasteners that need to be removed to pull back the liner. You should now be able to see two or three fasteners (plastic or metal) that hold the lamp assembly to the body. Remove these and pull the lamp assembly out to the rear. Remove the bulb holders from the lamp assembly by twisting them a quarter turn counter clockwise, then remove and replace the non-functioning bulb. Reverse to reassemble.

Open trunk and remove about 7 nuts from entire length of inside lid and entire assembly comes off

3 wing nuts. here is the info needed.

Hello! Working from the trunk:
1. locate the 2 retaining knobs that you fasten the trunk cargo net to and remove them...Look for the hard plastic trunk liner near to and inside of the rear light assembly. Unscrew the knobs.
2. Pulling back the plastic liner, locate the 4 studs (threaded posts). 3 will be located vertically in a line, the fourth, outboard and lower. Using a 10mm wrench(small), remove 3 of the 4 nuts fastening the light assembly to the body. DO NOT remove the lowest nut of the 3 in a vertical line, as this does not fasten the light assembly... Working from the rear of the car:
1. Hand pull the light assembly from the car body.
2. Remove bad lamp. Twist lamp socket and pull out of assembly. Pull lamp and replace with #3057.

Reassemble:
1. Test light prior to reassembly.
2. Ensure Gasket material for assembly and studs is intact, this keeps water/dust out and dampens movement (prevents rattling and increases the life of lamp).
3. Use Reverse instruction for reassembly.

To change any of the rear bulbs, first open the trunk. Pull any plastic clips from carpet near the lip of trunk by latch. Pull carpet (gently) away from the wall. Locate any screw caps and remove them. After all are removed, gently push on the threaded rods until the entire light assembly is out far enough to grab and pull outward. To change the bulb, simply grasp the retaining clip and with a slight push on the locking tab, turn it about a 1/4 of a turn counterclockwise (or clockwise) and pull out. Installation is the reverse of removal.

The procedure is as follows:-- Working from the trunk:
1. locate the 2 retaining knobs (doohickeys that you fasten the trunk cargo net to) for the Hard plastic trunk liner near to and inside of the rear light assembly. Unscrew the knobs.
2. Pulling back the plastic liner, locate the 4 studs (threaded posts). 3 will be located vertically in a line, the fourth, outboard and lower. Using a 10mm wrench(small), remove 3 of the 4 nuts fastening the light assembly to the body. DO NOT remove the lowest nut of the 3 in a vertical line, as this does not fasten the light assembly. DON'T LOSE THE NUTS OR WASHERS.

Working from the rear of the car:
1. Hand pull the light assembly from the car body.
2. Remove bad lamp. Twist lamp socket and pull out of assembly. Pull lamp and replace with #3057.
Reassemble:
1. Test light prior to reassembly.
2. Ensure Gasket material for assembly and studs is intact, this keeps water/dust out and dampens movement (prevents rattling and increases the life of lamp).
3. Use Reverse instruction for reassembly. -------------- The taillight/backup light/license plate light assembly is separate from the brake light/turn signal light assembly on the Buick LeSabre. No matter what rear bulb you have to replace, you must access the trunk area to do so. Open the trunk of the Buick LeSabre.Locate 7 nuts underneath the trunk lid (3 on each end of the trunk lid and 1 in the middle). Remove each one using a nut driver.Manipulate the trunk lid at chest level and gently pull the rear taillight assembly slightly away from the trunk lid.Locate the burned out bulb sockets and then remove the bulbs. Insert the new bulbs into the socket and test by turning on the lights before reassembling.Replace the tail light assembly by aligning the studs inside the predrilled holes in the trunk lid. Refasten the 7 nuts.Remove the cargo net if applicable to replace the brake and/or turn signal light.Unscrew the plastic wingnut that the cargo net is attached to. Pull back the trunk liner.Remove the 2 plastic wingnuts under the trunk liner.Pull the brake light assembly outward from the back of the LeSabre.Locate the socket of the burned out bulb and then turn counter clockwise 1/4-inch to release it from the assembly.Remove the old bulb from the socket and replace with a new one. Test the light before reassembling. Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.

open trunk, remove the plastic panel around the latch plate, remove the plastic mounting bolts that hold the grey trunk liners in place, there are two 10mm nuts that hold in the light remove nuts pull out light twist the bulb retainer out and replace bulb.

in your trunk you should see 4-6 plastic screw fasteners unscrew these the whole assembly will come out take the bulb that bad out turn counter clockwise replace bulb reverse the process. (fyi)your screw fasteners may be behind the fabric that lines the trunk just pull this out of the way.

Rear tail lamps for the 2002 La Sabre has eight nuts that hold the cover in place ( one piece-all acroos the back of the car). Do not remove the nuts for the lock, the cover sits in place and is not secured to the lock. Use a 10 mm deep well socket. remove the nuts and lift the cover to replace the burned out bulb(s). The bulbs are #194 or #198 (very small bulbs), not the 3057. It is easy to locate the burned out bulbs by putting the car in reverse and shutting off the engine and then put the ignition key in the accessory mode. The lights will light unless they are burned out. Simply pull them out and replace with the new ones and put the cover back in place and secure the nuts.
