Why is one of the Buick LaCrosse daytime running lights not working?
1 Answers
Buick LaCrosse daytime running light not working may be caused by a burnt-out bulb or a blown fuse. Burnt-out bulb: When the turn signal switch is turned to the left or right, the turn indicator flashes faster than normal. This symptom indicates that the turn signal bulb on that side is burnt out, or there is poor wiring or grounding of the turn signal. If the bulb is burnt out, replace the bulb; if there is poor wiring or grounding, handle it as appropriate. Blown fuse: If both left and right turn signals are not working, the possible causes may be a blown fuse, a faulty flasher, a malfunctioning turn signal switch, or an open circuit in the wiring.
