How do you clean rear sunroof drains on '06 Explorer?
 

How do you clean rear sunroof drains on '06 Explorer? I can't seem to see the rear drains. Do I have to drop the roof liner to get access or is there a way to blow them out from their exit point? BTW, I haven't found their exit yet, so knowing where they exit would be helpful as well.

I'm getting an intermittent leak with water coming through the map light. I've resealed all screws and around the inserts for the luggage rack. I've also tried running water through the front drains which seems to be unclogged.

On my 97 Mountaineer, I had to drop the front portion of the headliner to see the drain holes. I then used an air compressor to blow the debris out.

Thanks. I took mine to a leak specialist, so it is just as well that I didn't try to drop the roof liner. They determined that the windshield was the leak, so it will be reinstalled after a minor bit of rust repair.
