This procedure covers the removal and replacement of windshield wiper blades on the 2025 Rivian EDV 500 commercial delivery van, including recalibration of the wiper system.

Warnings

Tools required

Parts

• Driver side wiper blade assembly × 1 — Rivian OEM 26-inch blade with rain sensor compatibility
• Passenger side wiper blade assembly × 1 — Rivian OEM 22-inch blade with rain sensor compatibility
• Wiper arm alignment tool × 1 — Rivian service tool or equivalent

Preparation

1. Park vehicle on level surface and engage electronic parking brake
2. Ensure vehicle is in Park mode and power is ON but ready-to-drive is OFF
3. Connect Rivian Diagnostic Software to vehicle OBD-II port
4. Navigate to Body Control Module and enable 'Service Mode - Wiper System'
5. Use RDS to move wiper arms to service position (vertical/maintenance mode)
6. Clean windshield thoroughly with isopropyl alcohol to remove contaminants
7. Verify rain sensor lens is clean and undamaged
8. Document current wiper blade orientation and park position with photos

Procedure

1. 1

   Disable automatic wiper system
   Using Rivian Diagnostic Software, navigate to Vehicle Settings > Body Control Module > Wiper Control. Select 'Disable Rain Sensor' and 'Disable Auto Wiper Function'. Confirm system shows 'Manual Mode Active' on dashboard. This prevents the wipers from activating during blade removal.
2. 2

   Position wiper arms for service
   In RDS, select 'Wiper Service Position'. The wipers will move to a vertical position away from the hood. Wait for confirmation message 'Wipers in Service Position - Safe to Remove Blades'. If using manual method, turn ignition off mid-wipe cycle (not recommended for EDV 500 due to calibration requirements).
3. 3

   Remove driver side wiper blade
   Lift the wiper arm away from windshield until it locks in raised position. Locate the blade release tab on the wiper arm connection point. Press the tab firmly while sliding the blade assembly downward along the wiper arm hook. The blade should release with moderate pressure. Note the blade orientation and connector type for installation reference.
4. 4

   Inspect driver side wiper arm and spindle
   Examine the wiper arm for cracks, bending, or corrosion at the spindle connection. Check the heated park zone connector (small 2-pin connector near base) for corrosion or damage. If connector shows green corrosion, clean with electrical contact cleaner and dry thoroughly. Verify spring tension by gently pulling arm away from windshield - it should return firmly but not violently.
5. 5

   Install new driver side wiper blade
   Align the new blade assembly with the wiper arm hook, ensuring the adapter is correctly oriented (arrow on adapter points toward blade tip). Slide the blade upward onto the hook until you hear a distinct click. Gently tug the blade downward to confirm it is locked in place. Lower the wiper arm slowly back to the windshield, supporting it to prevent impact damage.
6. 6

   Remove passenger side wiper blade
   Repeat the removal process for the passenger side blade. Lift wiper arm to locked raised position, press release tab, and slide blade assembly downward off the hook. Note that the passenger side blade is shorter (22-inch vs 26-inch) and uses the same connection mechanism but different blade profile.
7. 7

   Inspect passenger side wiper arm
   Perform the same inspection as driver side: check for physical damage, verify heated park zone connector condition, and test spring tension. The passenger side experiences less wear but should still be thoroughly inspected. Clean any corrosion from electrical contacts.
8. 8

   Install new passenger side wiper blade
   Install the new 22-inch passenger blade using the same technique: align adapter with hook, slide upward until it clicks, verify lock engagement with gentle downward tug, then lower arm carefully to windshield. Ensure blade sits flat against glass across entire length without gaps.
9. 9

   Return wipers to park position via RDS
   In Rivian Diagnostic Software, select 'Exit Service Position' in the Wiper Control menu. The system will automatically move wipers to the park position (lower windshield area). Monitor the movement to ensure smooth operation without binding or unusual noises. Do not manually force wipers to park position.
10. 10

    Calibrate wiper system pressure sensors
    Navigate to RDS > Body Control Module > Wiper Calibration. Select 'Calibrate Blade Pressure Sensors'. The system will perform multiple wipe cycles at various speeds to learn the new blade characteristics. This process takes approximately 3-5 minutes. Keep windshield wet during calibration - spray liberally with windshield washer fluid.
11. 11

    Re-enable rain sensor functionality
    In RDS, navigate back to Wiper Control settings. Select 'Enable Rain Sensor' and 'Enable Auto Wiper Function'. The system will run a self-test of the rain sensor array. Confirm that status shows 'Rain Sensor Active - No Faults'. If faults appear, verify blade alignment and repeat calibration.
12. 12

    Perform wiper system verification test
    Using RDS test functions, cycle wipers through all speed settings: intermittent, low, high, and single wipe. Verify smooth operation without chatter, streaking, or blade lift at high speed. Test heated park zone function by activating defrost mode - wipers should return to park position and heating elements should activate within 30 seconds in cold conditions.
13. 13

    Clear service mode and verify integration
    Exit Service Mode in RDS by selecting 'Complete Wiper Service'. The system will finalize calibration and integrate wiper data with ADAS systems. Verify that no warning lights appear on instrument cluster. Check that forward collision warning system shows 'Active' status, confirming wiper replacement has not affected sensor calibration.

Reassembly

1. No disassembly was required for this procedure
2. Ensure both wiper blades are securely locked onto wiper arms
3. Verify heated park zone connectors are clean and properly seated
4. Confirm all diagnostic software connections are disconnected before driving

Verification

• Start vehicle and verify no warning lights related to wiper system or ADAS appear on instrument cluster
• Test wipers in all modes: single wipe, intermittent (all speeds), low speed, and high speed
• Spray windshield with washer fluid and verify even wiping pattern with no streaks or missed areas
• Test automatic rain sensor by spraying water on rain sensor area - wipers should activate within 2-3 seconds
• Verify wipers return to correct park position at bottom of windshield after operation
• In cold weather, confirm heated park zone activates when defrost is selected (wiper area should warm to touch within 2 minutes)
• Drive vehicle at various speeds up to 65 mph and verify no blade lift, chatter, or unusual noises
• Confirm forward collision warning system remains active with no ADAS-related fault codes
• Use RDS to verify Body Control Module shows 'Wiper System: All Functions Normal' status
