1997 Chevy 4 window leak

[Bigbobsaget]

So far my wife and I have barely got the bus home without replacing a battery and alternator. Now we find the headliner is drenched.
Has anyone else had a leak up front? I see along the roof line where the bus top begins there’s cracking in the paint.
I’m hoping to remove the head liner and magically see day light but if I don’t find any sign of where it’s coming from I plan on tarring the area above the windshield before the bus top begins.
Anyone else have similar issues?

The joint between the Chevy cab and bus body on mine leaked at both ends of the windshield. Basically it looked like the sun visors were leaking when I drove in the rain. I ran seam sealer along that front seam and it seems to be fixed. The foam/rubber gasket they put in doesn't seem to last the 15-16 years my bus has been around.
