I tore into the wire harness for the trailer hook up, this appears to be a factory option on this modle. I found no bare or shorted wires, than I unplugged the harness where it is located behind the inner body pannels on the rear right side. I also unplugged all 3 flasher unites from the harness.
I replaced the dual flasher found under the glove box by removeing the access door from the glove box.
Still blowing 20 amp fuse's
So I locate the multi function control for the hazards, signal, wipers, and dimmer switch and unplug it(not a fun job).
Try another 20amp fuse, this time it did not blow, hopefully when I get a replacement multi function control switch it will solve the problem.
