2022 R1T Cabin Air Filter DIY Replacement Guide

The cabin air filter is a crucial component for maintaining air quality inside your Rivian and is a common DIY maintenance task.

When to Replace:

1. Rivian generally recommends checking/replacing the cabin air filter every 15,000 to 20,000 miles or once a year, whichever comes first. This can vary based on driving conditions (e.g., dusty environments).
2. Symptoms like reduced airflow, musty odors, or increased allergies inside the cabin are strong indicators it's time for a change.

Causes of Reduced Airflow:

• Clogged Filter: The most common cause is a dirty filter accumulating dust, pollen, leaves, and other debris, restricting air passage.
• Debris in Blower Motor: Less common, but sometimes larger debris can get past a failing filter or through vents and partially obstruct the blower motor.

DIY Replacement Steps:

1. Locate the Filter: In the Rivian R1T, the cabin air filter is typically located behind the glove compartment. You'll need to open the glove box fully.
2. Access Panel Removal: Gently press in on the sides of the glove box to release its stoppers, allowing it to swing down further. You may need to disconnect a small dampener arm on the right side.
3. Filter Housing: Once the glove box is out of the way, you should see a rectangular access panel, often secured by clips or small screws. Release these to open the housing.
4. Remove Old Filter: Note the direction of the airflow arrow on the old filter (usually pointing down). Carefully pull out the old filter.
5. Install New Filter: Insert the new filter, ensuring the airflow arrow points in the correct direction (typically down, towards the cabin). Make sure it sits snugly in the housing.
6. Reassemble: Close the access panel, reattach any clips or screws, re-engage the dampener arm, and push the glove box back into place until it latches properly.

When to See a Shop:

• If, after replacing the filter, you still experience significantly reduced airflow, unusual noises (like a grinding or squealing), or persistent odors, it might indicate a more complex issue. This could include a failing blower motor, issues with the HVAC blend doors, or a problem within the climate control system itself. In such cases, professional diagnosis is recommended. While an OBD-II scanner won't typically show codes for a clogged filter, it might reveal HVAC system faults if a component like the blower motor is failing (e.g., P0530 - AC Refrigerant Pressure Sensor Circuit Malfunction, though this is less common for just a blower issue).
