Default left turn signals not working but dash blinker blinks?

i have a 02' f4i that is having a interesting issue. bad ground some where maybe? anyway the front and rear turn signals do not work at all but the dash blinks like normal. the previous owner put in led front/rear that are 2 wire so i have no running lights (which ill fix) just curious if anyone has ran into this issue as well and can point me in the right direction to look? thanks!

update:

found the left side front was wired wrong and then the rear bulb was corroded. before i went to ride fri night both sides blinked and so did the dash. after 10 miles into the ride the left side would blink when it felt like it and when it did not the dash would just light up the arrow not blink. the right side does not work at all now. when u hit the right signal switch it dims the headlight light for 1 sec. dash doesnt blink. any idea's? im a wiring newb

It could be a number of things but hopeful its just bad wiring and/or loose or corroded connections. Use this: Convert 2 wire signals to 3 wire to clean up the front turn signal wiring and restore the running lights. I used this and it worked great.

Just in case, this is the wiring diagram for the rear turn signals.


Hope this helps
