Common Causes

The issue of windshield wipers not turning off in a 2011 Ford F150 is often caused by a faulty multifunction switch. This switch controls various functions, including the windshield wipers, and can malfunction due to wear or electrical issues. Other potential causes include:

  • Faulty wiper relay
  • Damaged wiring
  • Malfunctioning park switch
  • Corroded or dirty contacts

DIY Solutions

Before replacing any parts, try these simple fixes:

  • Clean the multifunction switch contacts with electrical cleaner
  • Check and clean the wiper relay
  • Inspect wiring for any visible damage
  • Ensure the park switch is functioning correctly

If these steps don't resolve the issue, you may need to replace the multifunction switch.

Replacing the Multifunction Switch

Follow these steps to replace the multifunction switch:

1. Disconnect the battery

2. Remove the steering column covers (usually held by 5.5mm bolts)

3. Locate the multifunction switch (attached to the steering column)

4. Unplug the electrical connector

5. Remove the retaining screws (typically T10 Torx)
