2022 Chrysler Voyager AC Smells & Poor Airflow - Cabin and Engine Air Filters?

Vehicle: 2022 Chrysler Voyager LXi

Hey everyone,

I own a 2022 Chrysler Voyager LXi, and lately, the AC has been smelling a bit musty, especially when I first turn it on. Also, the airflow doesn't seem as strong as it used to be. I've got about 40,000 miles on it now, and I don't think I've ever changed the cabin air filter or the engine air filter.

Could these be the culprits? Are they easy to replace myself on the Voyager? What's the recommended interval for changing them, and where are they located? Any tips for a DIY replacement would be super helpful!

Thanks in advance!

Hi Emily,

Your instincts are spot on! The symptoms you're describing – musty AC smell and reduced airflow – are classic signs that your cabin air filter is clogged. A restricted engine air filter can also contribute to reduced engine performance and fuel economy, though it's less directly related to the AC smell or airflow inside the cabin.

Both the cabin air filter and the engine air filter are very common and relatively easy DIY maintenance items for your 2022 Chrysler Voyager LXi.

1. Cabin Air Filter:

  • Location: In most Chrysler Voyagers (and Pacificas), the cabin air filter is located behind the glove compartment.
  • Symptoms of Clog: Musty odors (often from mold/mildew growing on trapped debris), reduced airflow from the vents, increased strain on the blower motor.
  • Replacement Interval: Generally recommended every 15,000 – 25,000 miles or once a year, more frequently if you drive in dusty environments or have allergies.
  • DIY Steps:
    1. Empty your glove compartment.
    2. Open the glove compartment and usually, there are clips or a dampener arm on the side that you'll need to release to allow the glove box to swing down further.
    3. Once the glove box is fully lowered, you'll see a rectangular access panel (often with clips or tabs) for the filter housing.
    4. Open the panel, slide out the old filter, noting the airflow direction arrow.
    5. Insert the new filter, ensuring the airflow arrow matches the direction of air movement.
    6. Close the panel and reassemble the glove compartment.

2. Engine Air Filter:

  • Location: Under the hood, typically in a large plastic housing connected to the engine's air intake tube.
  • Symptoms of Clog: Reduced engine performance, decreased fuel efficiency, potentially a 'dirty' engine sound.
  • Replacement Interval: Generally recommended every 30,000 miles or 2-3 years, or as specified in your owner's manual. Inspect it annually.
  • DIY Steps:
    1. Locate the air filter box, usually a rectangular or square plastic housing.
    2. Unclip the metal clips or unscrew the screws holding the top of the airbox cover.
    3. Lift the cover and remove the old, dirty filter.
    4. Clean out any leaves or debris inside the airbox.
    5. Insert the new filter, ensuring it fits snugly.
    6. Replace the cover and secure all clips/screws.

When to See a Shop:

  • If changing both filters doesn't resolve the issues, particularly the musty smell, you might have a deeper issue like a clogged AC drain tube or mold growth directly on the evaporator coil, which would require professional service.
