Hi we did drive the 2020 Thor Synergy back up to the dealer. They replaced the wiring and the sensor. The service tech said that he could see where others had previously patched the wiring. This time they actually replaced the wiring. It’s been a week or so that we’ve had it back home. We’ve checked it several days in a row and all appears to be working now. Hoping that you are able to get yours working as well.
