Question about 2004 Buick LeSabre

1 Answer



Working from the trunk.

1. Locate and remove the 2 retaining knobs (doohickeys that you fasten
the trunk cargo net to) on each side that hold the hard plastic trunk
liner to the rear light assemblies.

2. Move the plastic plate that holds the spare tire back away from the
plastic trunk liner. This releases the bottom of the plastic piece.

3. With a large screw driver, pry the long plastic piece that goes
from side to side by prying up from the bumper. It's held in place by
some push in holders. Remove the large plastic piece.

4. Locate the 5 studs (threaded posts) on each light assembly. Three
will be located vertically in a line, and the other two will be

5. Using a 10 mm socket remove 4 of the 5 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 to the car.

6. Hand pull the light assembly from the car body.

7. Remove the bad lamp. Twist lamp socket and pull out of assembly.
Pull the lamp and replace with a # 194.

8. If replacing a tail lamp replace with a #3057 (book says #3357).

9. Test light prior to reassembly.

10. Ensure gasket material for assembly and studs is intact. This
keeps water/dust out and dampens movement (prevents rattling and
increases the life of the lamps).

11. Use reverse instruction for reassembly.

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.

There should be a flasher plugged into your fuse box of attached to two wires under your dash. REplace that and see if it is fixed.

1999 buick lesabre my right signal doesnt blink it stays solid , my left turn signal blinks fine i have to manually blink the right side every turn , i put the hazard lights on and the front left and right...

The easiest thing for you to do would be to replace the bulbs that are on that circuit. You should have one or two bulbs with a double filament, one for the brake and turn signal and one for the tail light.
If that does not fix the problem, someone will need to check the circuit for power from the turn signal switch. It takes all of the lights on one side to make the turn signal flash.

2004 buick lasabre, right side turn signal blinking fast.

Check the front turn signal bulbs. This will affect the resistance in the circuit and cause the working light to flash at a much faster rate.

Which bulb is the rear blinker on a 2001 LeSabre?

Its the large bulb.
The small bulb is the side marker bulb. The larger bulb (3057 or 3157) is the combo tail-stop-turn signal.
There is also a single filament bulb for the backup light.

Turn Signal Fuse or switch replacement? '93 buick lesabre?

Yes all the wiring needs to be complete. Then all the bulbs must be inserted into sockets. left side marker right side front turn back turn reverse lights brake light everything. Then make sure they all work. The problem could even be a bulb thats on the fritz ready to blow but still on and dim little light. if that's all fine then it's probably your flasher. There are 2 flashers one for turn and one for hazards but I think they are the same but still separate. located under dash on either side of the steering wheel. The flasher closest to the door is up in there pretty far it's size is about like a 2 liter cap and it's silver. good luck

Turn signal lamp burnt out

I think you have to open the trunk, lift the carpet back and there should be things that look like plastic knobs that have the bulb inside them, Should be 1157 or so bulbs.
