This procedure covers the removal and replacement of the wiper switch assembly on the steering column of a 2024 Rivian EDV 500 electric delivery van.

Warnings

Tools required

Parts

• Wiper switch assembly × 1 — Use OEM specification
• Steering column cover clips (if broken) × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Ensure vehicle is powered off and key fob is removed from the cabin
3. Open the front hood and locate the 12V battery in the front compartment
4. Disconnect the 12V battery negative terminal using a 10mm socket
5. Wait at least 2 minutes for airbag system capacitors to discharge
6. Position the steering wheel in the straight-ahead position before beginning work
7. Adjust the steering column to its lowest and most extended position for access

Procedure

1. 1

   Remove lower steering column covers
   Use a trim panel removal tool to carefully release the clips securing the lower steering column cover. There are typically 4-6 clips around the perimeter. Gently pull the lower cover away from the column and set aside. Note the location of any wire harness clips attached to the cover.
2. 2

   Remove upper steering column covers
   Locate the T20 Torx screws (typically 2-3) securing the upper steering column cover halves together. Remove these screws and carefully separate the upper cover halves. Disconnect any courtesy lighting connectors if equipped. Remove the upper covers and set aside with their fasteners.
3. 3

   Identify wiper switch location and harness routing
   Locate the wiper switch assembly on the right side of the steering column (driver's perspective). Identify the main electrical connector and note the harness routing through any retention clips on the column. Take a photo for reference during reassembly if needed.
4. 4

   Disconnect wiper switch electrical connector
   Press the locking tab on the wiper switch electrical connector and carefully pull the connector straight away from the switch. If the connector is difficult to access, use needle nose pliers to depress the locking tab. Do not pull on the wires themselves.
5. 5

   Remove switch retention fasteners
   Locate the T30 Torx screws (typically 2) that secure the wiper switch mounting bracket to the steering column. Remove these screws completely and retain them for reinstallation. Note the position of any shims or alignment tabs.
6. 6

   Remove wiper switch assembly
   Carefully slide the wiper switch assembly away from the steering column. The switch may have a keyed fit or alignment features. Note the orientation and any locating pins before fully removing. Release any wire harness clips securing the harness to the column.
7. 7

   Inspect mounting area and clean surfaces
   Examine the steering column mounting surface for any debris, damaged clips, or worn components. Clean the mounting surface with a lint-free cloth. Check the electrical connector on the column harness for bent pins or corrosion. Repair as necessary before proceeding.
8. 8

   Install new wiper switch assembly
   Position the new wiper switch assembly onto the steering column, ensuring proper alignment with locating pins or keys. Slide the switch into position until it seats fully against the column. Verify that the switch lever operates smoothly through all positions without binding.
9. 9

   Install switch retention fasteners
   Insert the T30 Torx screws through the switch mounting bracket and thread them into the steering column. Tighten the screws evenly in an alternating pattern to ensure proper seating. Tighten to a firm, snug fit without overtightening the plastic components.
10. 10

    Reconnect electrical connector
    Align the wiper switch electrical connector and press it firmly into the switch until the locking tab clicks into place. Gently tug on the connector to verify it is fully locked. Route the harness through any retention clips on the column to prevent interference with moving parts.
11. 11

    Reinstall steering column covers
    Position the upper steering column cover halves around the column and align them carefully. Reconnect any courtesy lighting connectors. Install the T20 Torx screws and tighten securely. Install the lower steering column cover by aligning the clips and pressing firmly until all clips engage with audible clicks.
12. 12

    Reconnect 12V battery
    Return to the front hood and reconnect the 12V battery negative terminal. Tighten the 10mm nut securely. Close the hood.

Reassembly

1. Ensure all steering column covers are properly clipped and secured with no gaps
2. Verify all electrical connectors are fully locked and harnesses are properly routed
3. Check that the wiper switch lever moves smoothly through all positions without interference
4. Confirm the steering wheel can rotate freely without binding on covers or harnesses

Verification

• Power on the vehicle and verify the instrument cluster displays no new warning lights related to the wiper system
• Test all wiper switch functions: intermittent (all speeds), low speed, high speed, and single wipe
• Test the washer function by activating the switch and verifying proper spray and wipe operation
• Verify that wipers return to the park position correctly after each operation
• Check that all steering column cover panels are secure with no rattles or loose components
• If equipped with Rivian service software, check for any diagnostic trouble codes and clear if related to the repair
• Verify steering angle sensor calibration if required by the vehicle system
