Remove dash plastics and check all open plugs for debris, moisture and or metallic dust. Especially under the cup holder. While there look for any chaffed wiring also. Clean plugs with contact cleaner and compressed air. The plug associated with this will more than likely be located near the cup holder next to the right OHG post. Let us know what you find. But any open connector will be fair game to check.
