2006 Buick Lacrosse - The headlight (DIM) will stop working and then a day or two later start back. Took back to where it was purchased and they said they had it fixed but happened the very same day. Any ideas?

The bright light fitting is the same as the dim so take it apart fist to see how the cover screws off/on and the light comes out. Both the cover and the bulb are removed by a standard twist to the counterclockwise and replaced by a twist to the clockwise. 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. 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. 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. 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. If not, then you need 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. To remove these locking pins, pull or pry up the little tab in the center of the pin just like you were pulling a nail by the head. That should give you a little more space.

The relay under the hood may have gone out. We had the same problem on our 2007 Buick LaCrosse CX. The bulbs were fine, high beams worked, all turn signals and everything except the low beams turned on. Turns out the relay had gone bad.

SOURCE: HOW DO I CHANGE THE
Asuming you mean taillight/turnsignal, and not highmounted brake light:
1.open the trunk
2.Remove 4 wingnuts on trunk trim (there are two on each side)
You can do it by only removing 2 on one side, but it makes a nicer job,
3.Pull back the trunk "trim" the carpeted cardboard
4.Remove 2 wingnuts which hold the taillight assembly in place
Pull out the taillight assembly; you might want to remove (i.e. unattach or unplug) the wiring harness
5.Turn the particular bulb's socket (there's 5 back there: 2 tail, 1 back up, 1 side marker, 1 brake/turn) counterclockwise, and it removes from the assembly, holding the bulb.
6. Pull out bulb and replace.
6. Reverse steps to reassemble.
