2005 Chrysler PT Cruiser leak

PT has developed a leak that flows into the passenger side
footwell, and then into the rear footwell. Many attempts to
fix to no avail.

Check the AC drain?

Do you have a sunroof? If so, a drain line could be blocked. I’ve never cleaned one myself, but I often read that it can be done with string trimmer line.

What fixes have you done so far???
