    I have a 2020 4 runner, three rows of seats
    We have an apparent roof leak. Could this be the back antenna? Or the gutters? The rubber strips capping the gutters came off but when I attempted to put them back on I saw they didn’t fit tight so they must not be a water seal.
    Anyhow, they are not on.
    The water is dripping to the back ceiling. We do have a skylight but haven’t seen a leak near it.
    any help appreciated.

    Welcome to the forum.

    I would first check that each corner sunroof drain is free and clear, Any slight obstruction can cause water to not drain and eventually run over the frame assembly into the interior.

    From there have someone spray water on the roof/points you feel may be issues and monitor from the inside.

    Leaks can drip a distance from the actual source location, I too suspect skylight.

    Those rubber strips came loose on my 2022 so i reached out to a friend whose a toyota mechanic. He said to apply some silicone to hold them in place. That was probably 3 years ago and ive had no issues
