im assuming you have traced the fuel line from front to back,its likely in fuel tank and only serviceable by removing tank. call auto parts or dealer to be sure

Start simple. Investigate your fuses, since it is unlikely, but not unheard of, for both low beams to fail simultaneously.
Do you know where your fuses are?

Both my remotes no longer work. I will be ordering new ones off Ebay and having my dealer program them. New ones from Buick are very pricey.

The procedure to replace head light assembly on buick lacrosse is as follows:---
1)To remove and replace the headlight assembly you will need to remove 1 retaining bolt on the top of the headlamp assembly and 2 sliding retainers at the rear.
2) The carefully Pull up the retainers and that will release the headlight assembly and allow you to pull it out the front.
3) When installing the new headlight assembly make sure you have it lined up correctly before trying to install the retainers, don't force them it may get cracked .
4) Both the cover and the bulb are removed by a standard twist to the counterclockwise and replaced by a twist to the clockwise.
5) Now to the dim light. You have to release the entire light assembly before you can remove the screw-on cover to reach the light.
6) On the rear edge of the light unit closest to the engine is a white locking tab. Pull that tab up just to the point where it releases…pull too far and it locks again.
7) Next, locate the other locking bracket which is a metal bracket in the center-rear of the light assembly. This bracket is held down by a screw.
8) Remove the screw with a 10mm wrench. Lift the bracket just like you did the white bracket. You should now be able to pull (or pry) the entire light unit forward a little. Depending on the size of your hands this might be enough.
Note:-- The turn signal is part of the headlight assembly on your 2005 Buick LaCross.
9) To replace the headlight bulb you need to remove the front bumper cover.
10)To release the plastic bumper assembly to give you a little more space. This is done by removing two expansion locking pins, one that holds the little plastic strip down between the bright and dim lights and one that is located inside a rubber bumper on the engine side of the light unit.
11)To remove these locking pins, pull or pry up the little tab in the center of the pin.

I just changed the low beam bulb in a '05 Buick LaCrosse and found it really rather easy after researching it. I found no reason to remove the grill and the bumper cover, BUT you do have to remove the top 4 fastners that hold the grill assy to the radiator support, then you can work the headlight assy forward enough to work it out of the socket and turn it down so you can get to the bulb pockets on the back side. NO NEED to remove it all, just loosen it and gentley pry things forward enough to get the light assy out. ALSO> My supplier said his Wagner lighting book called for a 9006 bulb, but the car I worked took a H11. About 4x the money over a plain ol 9006 bulb but it might save someone picking up the wrong bulb. I hope this helps someone else out....Best of luck to you all
