Soon as I start car sometimes all lights flicker and sometimes while Im driving lights flicker and car shuts off starts back up car is 99 buick lesabre


Check all your ground wires. There will be several wires connecting
ultimately to the negative side of the battery. Usually at least 2
wires are connecting the body of the vehicle to the negative side
of the battery. Generally, the lights are grounded to the body which
is grounded either to the engine block or directly to the battery.

the headlights Flicker could be caused by the alternator. Local auto parts stores will test this vehicle charging system with their mobile analyzer and it will determine the problem...

Dash lights and headlights are flicker on my 2000 Buick LeSabre limited. Any solutions? Also the abs and traction control light won't go off.


Traction light is on because the abs is on.Traction control needs to have the abs system fully functioning to work.Most common cause of abs light is a wheel speed sensor.As for your lights flickering the alternator may be going out or you have a poor ground connection.Would check battery cables first to make sure they are tight.
