The driver flasher on my 2004 Buick Lesabre blinks very fast while there is no blink in the rear. I replaced the bulb and the problem still exist.
a fast flasher means a bulb is bad.or bad socket and or a ground.. change both bulbs on that side..also replace the flasher...all that stuff is cheap to buy and easy to change...then report back here...
Also check your front bulb on the same side.
Check both front and back bulbs. Just in case both went bad.
