My sister's and my brothers GM hardtops both leaked like yours is doing.
My sister got hers fixed, my brother opted not to do so.
The leaks turned out to be body leaks from the factory from water running in body openings at the windows and body joints.
I believe my sister had to have the fenders pulled off to fix it.
God bless your efforts.

Sounds like you have a cold solder joint somewhere in the dash assembly. My suggestion is to find a website that specializes in GM self repair, likely a known issue that has a simple fix but if you find someone who has already solved that problem will save you a bunch of troubleshooting.

Replace the fuel filter. Pray that fixes it cause if it doesn't it is probably that the pump is getting weak, and those are pricey.
