I have a 2007 expedition. The left turn signal flashes fast all the time. All bulbs are working. 4 way flashes all bulbs at normal speed.

I have changed the multi-function switch on the column, no change.

Any help / suggestions would be most appreciated.

Thanks John F

 

check your flasher relay...its on the driver side...underneath the dash...normally this happens when you put LED bulbs in...you should hear it blinking in sequence...
