2002 Mustang - left side signal flasher works fine, right side flashes fast, all bulbs work. Need some help on locating the problem to fix.

 

...flashing fast means that the front or rear bulb is out on that side...I would just replace both to start!

 

I'll give that a try tonight.

Thanks.

 

Replaced bulbs....same problem....fast flashing on left side.

Any ideas?

 

My problem was a loose connection at the tail light side light bulbs. I wasn't sure at first so i bumped it whenever it started flashing fast and that fix it but it kept on happening. So I started messing around with all the connections and sure enough that is what it was.
