when you turn on the left turn signal it clicks. sometimes it blinks but only once or twice then stops and clicks. right signal works fine. left rear bulb looks fine. front bulb was burned out and i replaced. still does the same thing.

So when it stops blinking does it just stay on solid?Also do you have a test light to do some testing?

Sounds like a bad flasher but without atleast a test light we cant do much testing.

i thought the flasher controlled both sides. can it be bad and still work on right side. i can get a test light if it will make it easier to determine. cheaper than the dealer.

As you can see in the diagram i posted its more of a module and there is a fuse for the left and right turn signals make sure those fuses are good.Also make sure you get a computer safe test light.
