Also, when it rains heavily, there's water leaking into passenger seat area (under glove compartment, where your feet go) I found that the leaking is coming from some white container's rubber seal, but don't know what it is.
This is common on the 2nd generation integras. I think this is your problem. The are some rubber seals around the push screws for the front wiper cover area (cowl) that wears out over time. Water leaks through there. There's about 8 of them that needs to be replace. You can pick up the part for about 2-3 bucks each. I got the parts but haven't had time to swap them out yet. Check out the site if you haven't seen it before.
