Question about 2005 Buick LaCrosse
My dashboard lights, heater/ac lights, and interior lights are going from dim to bright to dim to bright very rapidly. (headlights, too but not as noticeable)
First, check that the battery connections are clean and not corroded. If not look for the ground wires that connect to the chassis. Check to see if any are corroded or loose. Finally if that has no effect, you have a short somewhere in your wiring. The easy way to isolate it is to pull the fuses for each device one by one and see if the dimming stops. The last one to cause the dimming is the problem. If it happens when you hit a bump it also might be a ground fault in the interior car grounds....good luck!

check the earth wire first,wattage on the bulbs in case their wrong or old type bulbs ,check supply voltage ,if all ok then fit aux spot lights .if still having a problem have eyes checked as over 40 the old peepers can deteriorate ,dont know the name of it but it can affect some people at a younger age than others,glasses will not correct this problem.

there should be 2 brackets at the rear of bulb housing, 1 may have a small bolt.....lift these up and the headlamp housing should come out. you will see how it works when you get it apart.

could be dimmer switch,may heat up and kill lights or maybe headlamp switch, your at a point were you are going to have to replace parts,first thing is headlamp switch, take apart but leave it pulged in when lights dont work install new switch and see if that works, this is not a diffuclt problem dont know why dealer could not pin point,anyway start there, good luck.
