2018 Focus – Horn Inoperative And/or Works Intermittently
Some 2018 Focus vehicles may exhibit an inoperative and/or intermittent horn operation.
Refer to Workshop Manual (WSM), Section 413-06 for diagnosis.
If testing leads to horn replacement, inspect connector C131 for corrosion and repair as necessary, using replacement pigtail 3U2Z-14S411-BXAB or Motorcraft WPT-984.
Using Rotunda Technician Tool program (RTTP) NUD105-R025E Flex probe kit or equivalent, verify pin drag on the C131 harness connector terminals.
If no corrosion is present, reconnect connector C131 a couple of times and add Motorcraft electrical grease XG-12 or equivalent meeting specification WSB-M1C239-A to both terminals.
For claiming, use causal part 13832 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual.
