@ernestyuse I wonder if this could be related to a bad really (combination Flasher) or the BCM (Body Control Module). Also check for corrosion. Check the wiring harness and the cables ends carefully. Corrosion increase resistance and poor contacts that may increase conductions as they heat up would be a possibility. I''d start with the flasher relay. Here is the [document|39922] Chapter for your model Jeep. Page 231 starts the Turn Signals sections.
