strange turn signal flasher pattern

my 2014 F150 has a sreange turn signal flasher pattern.

the right turn is a regular rate probally 60 flashes per minute

the left rurn is doing 120 per minute, really fast flash

the following has been done or observed
all bulbs are incandescent
all bulbs are lighting/flashing
all have been pulled and contacts cleaned
all marker / tail lights work
changed bulbs, makes no difference
looked for flasher, can hear but not see under dash, it does sound when flashing.

noticed that the sockets that hold all teh bulbs are brown ob the end near the bulbs, the rest is gray

what am I missing

thank you

You will need to read the BCM codes and see why it's complaining.

Forscan can read BCM codes and do a lot of other things.

Once you get the codes, please post them.
