71 hemi orange swinger rescue.

So found a bit of water running out of the fresh air vent on the drivers side. Leaking windshield wiper seals or cowl? Is it possible to empty the cowl of debris or is it the same song and dance with any classic from that era?
Possible, sure. Hard to get to the drains with the fenders on. Make sure they're not clogged. Blow, suck, blow suck. Go up through the vent holes (heater box and vents out) with homemade attachments for a shop vac. People even cut access holes in the firewall like the earlier cars had. Or tow it about 60 with the vents open!
