Tesla Model 3/Y Cabin Filter Replacement

To replace the cabin filters in a Model 3/Y and ensure proper installation, follow these steps:

1. Turn off the climate control system to prevent any airflow during the replacement process. 
2. Move the front passenger seat fully rearwards and remove the front passenger floor mat for better access.                                                           
3. Use a clip pry tool to carefully release the push clips that secure the front passenger footwell cover to the instrument panel. While supporting the footwell cover, disconnect the two electrical connectors and move the cover aside.                                       
4. Working from top to bottom, use a trim tool to carefully release the right side panel from the center console.                                                               
5. Locate and remove the T20 screw that secures the cabin filter cover to the heating, ventilation, and air conditioning (HVAC) module. Then, release the cabin filter cover and move it aside. If the screw is a T20/6mm hybrid fastener or tabs are present, follow the respective instructions.
6. Fold the upper cabin filter's tab upward and the lower filter's tab downward. 
7. Hold the tab on the upper cabin filter and pull it out from the HVAC module.
8. Repeat the same process for the lower cabin filter, holding its tab and pulling it upward and out.                                                                             
9. Take the new filters and ensure that the arrows on both face towards the rear of the vehicle. Insert the lower cabin filter into the HVAC module and lower it into place. Then, insert the upper cabin filter above it.                                           
10. Fold the tabs inward to prepare for the installation of the cabin filter cover.              
11. Install the cabin filter cover by engaging the lower cover tab and securing the T20 screw or T20/6mm hybrid fastener. Tighten the screw to 1.2 Nm/0.89 ft-lbs. If tabs are present instead of a screw, maneuver the top notch of the cabin filter cover into place, then secure the tabs at the bottom of the HVAC module.           
12. Reconnect the two electrical connectors to the components in the front passenger footwell cover. Once connected, resecure the cover with the push clips.                                   
13. Align the right side panel with the front and rear locator slots on the center console, and apply pressure until all the clips are fully secure.                                        
14. Reinstall the front passenger floor mat and move the front passenger seat back into its original position.                                                                                  

Remember to follow these instructions carefully and exercise caution during the replacement process to ensure a successful installation of the cabin filters in your Model 3/Y.
