Wipers immediately stopped working during heavy snow and rain mix. After spending a lot of money and time trying to repair they still did not work. All fuses and wires as well as wiper arms were inspected, the wiper motor and multifunction swith were replaced, my battery was replaced and no wipers. After verifying electrical circuits and power to the wiper motor, it was determined to be an issue in the tipm, apparently a frequent issue with Jeep vehicles. This is a dangerous issue that can cause accidents and certainly ds not allow a vehicle to pass a state safety inspection, as in my case. This is an expensive repair that Jeep should be responsible for bt recalling these units on the Wranglers that are so often affected!
