This may be due to water intrusion at the back side of the trailer tow connector. Inspect connector C4099 and the trailer tow connector (14489) for signs of corrosion or damage. If corrosion or damage is present at either connector, replace the female side of the C4099 connector using service pig tail kit (3U2Z-14S411-JXC) and the trailer tow connector.
