This would have been an extremely tough area to get paint or anything else into either by the factory or anyone else. quite likely its finally rusted through. You may be able to get your hand up there if you pull the heater grill off. Otherwise you'll have to drop the heater.

Exactly, I remove the cowel screens from time to time and use a shop vac. You can use air hose to blow out the drain holes too, I think there are 3 of them. Then I use the shop vac again to suck out whatever I moved around with the air hose.
