My right turn signal light use to blink fast then normal. Sometimes it would blink fast for a few days then all of a sudden back to normal. Now it just blinks fast and the passenger side front turn signal light doesn't come on at all. The side marker and the rear turn signal work but they blink fast. The left side is fine. I replaced all bulbs and that didn't help. Only the passenger side front turn signal doesn't work. If it were the flasher it wouldn't flash at all right? Could it be the socket/?Any help to save me from going to dealer is very much accecpted

Hello,

It sounds like the issue is with the socket.
A turn signal will hyper flash (fast flash), typically for a inoperative bulb.
Since putting a new bulb did not make the turn signal to work on that side, check to see if you are getting power to the socket.
If the socket is burnt replace it. If you do not have any power to the harness you might have a short in that harness. In that case you will have to trace the wire to find that short.

I have attached the wiring schematics for your reference

Please let me know of any questions.
Thank you.
