Tools required

Parts

• Wiper/turn signal multifunction switch × 1 — Use OEM Ford specification

Preparation

1. Park vehicle on level ground and set parking brake
2. Turn ignition to OFF position and remove key
3. Turn front wheels to straight-ahead position
4. Wait at least 1 minute after disconnecting battery before working on airbag system components

Procedure

1. 1

   Disconnect battery
   Open hood and disconnect the negative battery terminal using a 10mm socket. Secure the cable away from the battery post to prevent accidental reconnection. Wait at least 1 minute for airbag system capacitors to discharge.
   Torque spec

   Battery Terminal Bolts6 Nm (4 lb-ft)
2. 2

   Remove lower steering column covers
   Using a trim panel tool, carefully pry the lower steering column cover tabs to release them. There are typically 4-5 clips securing the lower cover. Remove the lower cover by pulling it down and away from the column. Set aside in a safe location.
3. 3

   Remove upper steering column cover
   Locate the upper steering column cover retaining screws (typically two T20 Torx screws at the bottom of the upper cover). Remove these screws, then release the clips at the top of the cover and remove the upper cover. Note the routing of any wiring harnesses.
   Torque spec

   Cover Screws14 Nm (10 lb-ft)
4. 4

   Disconnect wiper switch electrical connectors
   Locate the two electrical connectors on the back of the multifunction switch assembly. Press the locking tabs on each connector and carefully pull them straight back to disconnect. The larger connector is typically gray or black, the smaller connector may be for the turn signal function. Note their orientation for reinstallation.
5. 5

   Remove multifunction switch mounting screws
   Locate the two T30 Torx screws securing the multifunction switch to the steering column housing. These are typically positioned on the left side of the column. Remove both screws completely and place in a magnetic tray.
6. 6

   Remove multifunction switch assembly
   Grasp the multifunction switch lever and carefully pull the entire switch assembly straight out away from the steering column. The switch may require slight wiggling to clear the mounting bracket. Remove the assembly completely from the vehicle.
7. 7

   Install new multifunction switch
   Position the new multifunction switch assembly over the steering column mounting bracket, ensuring the switch shaft aligns with the column mechanism. Slide the switch into place until it seats flush against the mounting surface. Verify proper alignment before installing screws.
8. 8

   Install mounting screws
   Install the two T30 Torx mounting screws finger-tight first to ensure proper thread engagement. Once both screws are started, torque them to specification in a cross-pattern to ensure even pressure on the switch housing.
   Torque spec

   Module Mounting Bolts8 Nm (6 lb-ft)
9. 9

   Reconnect electrical connectors
   Reconnect both electrical connectors to the new multifunction switch, ensuring they click firmly into place. Verify the locking tabs are fully engaged by gently pulling on each connector. Match the connectors to their proper locations based on size and keying.
10. 10

    Reinstall steering column covers
    Position the upper steering column cover over the column, ensuring all wiring is properly routed and not pinched. Align the mounting screw holes and install the T20 Torx screws to specification. Snap the upper cover clips into place. Position the lower cover and press firmly until all clips engage.
    Torque spec

    Cover Screws14 Nm (10 lb-ft)
11. 11

    Reconnect battery
    Reconnect the negative battery terminal and torque the terminal bolt to specification. Ensure the cable is fully seated on the battery post before tightening.
    ⚠Do not overtighten battery terminal to avoid damaging the terminal post

Reassembly

1. Ensure all steering column cover clips are fully engaged and covers are secure
2. Verify no wiring is pinched between column covers
3. Check that multifunction switch lever operates smoothly through full range of motion

Verification

• Turn ignition to ON position without starting engine
• Test wiper switch in all positions: intermittent, low, high, and mist
• Test washer function by pulling wiper lever toward steering wheel
• Test turn signal function in both left and right positions
• Verify high beam and flash-to-pass functions operate correctly
• Check that turn signal self-canceling feature works after turning steering wheel
• Start engine and verify all wiper speeds function properly under load
• Check for any illuminated warning lights on instrument cluster related to multifunction switch
• If equipped, verify steering angle sensor does not require recalibration (no ABS or stability control warnings)
