My 2004 Grand Marques left turn signal indicator is flashing rapidly, like it would to indicate one of the turn signal bulbs is blown, but both front and back seem to be still flashing, so what else could it be?
There's 2 bulbs in each taillight assembly. Be sure both are working. HTH. -Jim
Thanks! I didn't realize that there were 2 bulbs associated with the tail light turn signal.
You're welcome. Glad to help. Thank you for the best answer click! -Jim
