This procedure covers the removal and replacement of the climate control module in a 2022 Rivian EDV 500 electric delivery van, including dashboard disassembly and electrical system integration.

Warnings

Tools required

Parts

• Climate Control Module × 1 — Use OEM Rivian specification
• Dashboard trim panel clips (assorted) × 1 — Replacement clips as needed
• Electrical connector dielectric grease × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Disconnect the 12V auxiliary battery negative terminal and wait 10 minutes for system capacitors to discharge
3. Using Rivian diagnostic software, place the high-voltage system in service mode and verify HV system is disabled
4. Document all climate control settings and module configuration for reference during reinstallation
5. Remove the driver's seat to improve access to lower dashboard area (optional but recommended)
6. Cover the steering wheel and driver's seat area with protective material to prevent damage

Procedure

1. 1

   Remove lower dashboard trim panel
   Using trim removal tools, carefully release the clips securing the lower dashboard panel below the steering column. Start at the bottom edge and work upward. Remove the panel and set aside with fasteners in a magnetic tray.
2. 2

   Disconnect driver's side knee bolster
   Remove the T25 Torx screws securing the knee bolster panel (typically 4 screws). Disconnect any electrical connectors for ambient lighting if equipped. Remove the bolster panel to expose the area behind the dashboard.
3. 3

   Remove center console lower trim
   Remove the lower center console trim panels to access the climate control module mounting area. Use trim tools to release clips along the sides and bottom. Disconnect any USB port connectors or 12V outlet wiring as necessary.
4. 4

   Access climate control module location
   The climate control module is located behind the center dashboard area, typically mounted to the HVAC unit housing. Use a flashlight to locate the module and identify all electrical connectors and mounting fasteners. Take photos for reference during reassembly.
5. 5

   Disconnect electrical connectors
   Locate all electrical connectors attached to the climate control module (typically 3-5 connectors including power, communication bus, and sensor inputs). Release the locking tabs on each connector and carefully disconnect. Label each connector position if not already keyed differently.
6. 6

   Remove module mounting fasteners
   Remove the mounting screws or bolts securing the climate control module to its bracket (typically T30 Torx or 10mm bolts). Support the module with one hand while removing the final fastener to prevent it from falling.
7. 7

   Remove climate control module
   Carefully extract the climate control module from its mounting location. Note the orientation and routing of any remaining connections. If refrigerant lines are integrated, ensure they are not damaged during removal (they should remain attached to the HVAC unit).
8. 8

   Prepare new climate control module
   Unpack the new climate control module and verify the part number matches the original. Apply a small amount of dielectric grease to each electrical connector terminal to ensure proper conductivity and corrosion resistance.
9. 9

   Install new module
   Position the new climate control module in the mounting location, ensuring proper orientation and alignment with mounting holes. Thread in mounting fasteners hand-tight, then tighten securely. Verify the module is firmly seated against its mounting surface.
10. 10

    Reconnect all electrical connectors
    Reconnect all electrical connectors to the new climate control module in their original positions. Ensure each connector clicks fully into place and locking tabs engage properly. Verify no pins are bent or misaligned.
11. 11

    Perform initial electrical verification
    Reconnect the 12V auxiliary battery. Using the Rivian diagnostic software, power on the vehicle systems and verify the climate control module is recognized by the vehicle network. Check for any communication errors or fault codes before proceeding.
12. 12

    Program and configure new module
    Using Rivian diagnostic software, program the new climate control module with vehicle-specific configuration data. This includes VIN programming, refrigerant type, cabin volume parameters, and sensor calibrations. Follow all on-screen prompts to complete the programming sequence.
13. 13

    Test climate control functionality
    With the vehicle in accessory mode, test all climate control functions including temperature adjustment, fan speed control, air distribution modes, defrost functions, and heated/cooled seat integration if equipped. Verify temperature sensors are reading correctly.
14. 14

    Reinstall all trim panels
    Reinstall the center console trim, knee bolster panel, and lower dashboard trim in reverse order of removal. Ensure all clips are properly seated and fasteners are tightened. Reconnect any ambient lighting or accessory power connectors. Verify all panels fit flush with no gaps or rattles.

Reassembly

1. Ensure all electrical connectors are fully seated with locking tabs engaged
2. Verify all dashboard trim panels are properly clipped and secured with no rattles
3. Replace any damaged trim clips identified during disassembly
4. If driver's seat was removed, reinstall and reconnect all electrical connections including seat position sensors and airbag connectors

Verification

• Using Rivian diagnostic software, perform a complete climate control system test and verify no fault codes are present
• Test all climate control modes including AUTO, defrost, floor, vent, and mixed modes to ensure proper air distribution
• Verify temperature control functions correctly with both hot and cold air delivery
• Check that HVAC blower operates smoothly at all speed settings without unusual noise
• Confirm climate control display shows correct information and responds to all inputs
• Test remote climate preconditioning function through the Rivian mobile app if equipped
• Verify cabin temperature sensors are reading ambient temperature accurately
• Road test the vehicle to confirm climate control operates normally under driving conditions
