Chevrolet, GMC - heater/cooling system... GRRR

The 1967 - 1972 Chevrolet & GMC Pickups Message Board - The 1947 - Present Chevrolet & GMC Truck Message Board Network - 67-72chevytrucks.com
It never ends. 1972 C20 with A/C.

New heater and radiator hoses.

100 miles later the water pump goes.

Replace the water pump and fan clutch.

20 miles later, I have a new leak that is baffling me.

I came home last night and when my headlights shone under the truck I noticed a wet spot on the driveway behind my right front tire. It was antifreeze. Oh great!

Shine a flashlight underneath and see where it has run down the firewall and dripped on the fender apron.

Open the hood and feel under the heater/AC case. Dry as a bone. Weird. Also dry inside just for reference.

Only damp place I see at all from the top side is a little on the bottom of the blower motor mounting flange. ???

I would have already pulled the blower motor to check further, but it appears that I have to remove the hood hinge to get the blower motor out.

Any direction you guys can offer on this clusterf?@# is appreciated.
