Turn signals won't work. But if you turn on the flashers & the right turn signal they will both work but if you turn on the flashers alone they will not work either I have replaced fuse and both flasher fuse's and all the bulbs I am lost need help please.

Hello,

It sounds like you might have an issue with the turn signal switch.
Unless you have already done, change your flasher relay out.
The flasher is located behind the instrument panel below the radio (see diagram below).
I think there might be a short in the multi function switch, which making the lights act strange.
You will have to trace the wires to see what has a short.

I have attached the wiring schematics for your reference.

Please let me know of any questions.

Thank you.
