why does my Acura MDX YF3 (2022-Present) have a strange smell coming from the vents

Solution

1. Preparation

• Gather tools and materials:
  • Screwdriver set
  • Flashlight
  • Replacement cabin air filter (if needed)
• Ensure the vehicle is parked on a level surface with the engine off.

2. Inspect and Replace Cabin Air Filter

• Sub-steps:
  1. Open the glove compartment and remove all contents.
  2. Locate the cabin air filter access panel, usually at the back of the glove box.
  3. Unclip and remove the access panel.
  4. Pull out the old cabin air filter and inspect for dirt or mold.
  5. If dirty, replace it with a new filter, ensuring the airflow arrow points in the correct direction.
  6. Reattach the access panel and return glove box contents.

3. Clean the HVAC System

• Sub-steps:
  1. Turn on the vehicle and set the HVAC system to the highest fan setting.
  2. Use a disinfectant spray or HVAC cleaner and spray it into the air intake (located at the base of the windshield) while the fan is running.
  3. Allow the system to run for 10-15 minutes to circulate the cleaner through the ducts.
  4. Turn off the HVAC system and let it sit for a few minutes.

4. Inspect and Clean Evaporator Coil (if necessary)

• Sub-steps:
  1. Remove any necessary dashboard components to access the evaporator coil.
  2. Visually inspect the evaporator for signs of mold or buildup.
  3. Use a soft brush and a cleaning solution to gently clean the coil.
  4. Allow it to dry before reassembling the dashboard components.
