Welcome, I'm Chris (aka Moose) I'm an independent contractor here at Just Answer.
Using the last page of the exterior lights diagram below. From the right turn fuse the wire splits and goes to the mirrors then to the fuse box. We need to test this wire at the fuse box to see if there is pulsing turn signal power there or not to see if the concern is in the fuse box or the wire to it.
Thanks for asking your question and letting me try to help you.
