New multifunction switch, New brake light switch, grounds checked and cleaned, light sockets cleaned and checked, New TYC brand rear lights,new led flasher, led front bulbs.
The issue is when turn signals are on, front flashes like normal. Rear flashes both sides. Apply the brakes and everything goes steady and flasher hyperclicks. Turn signals also apply trailer brakes.
I have changed multifunction switch twice. Ran new grounds for rear tail lights( lights got brighter).
I'm tempted to order another multifunction switch from a different company and try it. But I wanted to see if someone else has run across this problem first.
