bumping this thread since my car now sits out in the rain during the week for work.
How do I remove the headliner enough to access the REAR drain pain? Dropping the headliner enough to see the front is easy enough following the directions. The fronts are clear and I can push wire/weed whacker string up through the rear holes, but I don't know if perhaps one of the drain tubes is disconnected from the pan. My leak is on the rear passenger side roof area. Is it easier to remove the ultraview sunroof rather than the head liner?
Any help? This leak seriously has me considering a trade in on a new mustang.
