What's wrong?
The trailer tow module in the 2016-2018 Thor Motor Coach Compass and Gemini is an electrical control unit for trailer lighting on the Ford chassis. When a trailer is connected, the module helps send the right lighting signals from the motorhome to the trailer, including turn-signal and lamp commands. It sits in the driver's side footwell area, where it depends on dry wiring and protected connections.
On affected motorhomes, water can collect and splash in that footwell. Water that reaches the trailer tow module can corrode the wiring and create electrical faults. The filing lists rapidly flashing turn signals, loss of the instrument panel display, an electrical short, and seatbelt pretensioner deployment as issues tied to this condition.
There is no warning sign before failure. The first clue can be an electrical symptom after corrosion has already affected the module, such as fast turn-signal flashing or a blank instrument panel.
