Another water leak question:
I would look at the weather stripping for cracks/splits. it most likely has to be replaced unless the window isnt in alignment at the front of the A pillar while rolled up.

Condition 4
Water is running down the front edge of the door or water is on top of the sill plate.
Cause
The butyl strip under the seal at the base of the "A" pillar may not be sealing properly or the push-in fastener may not be seated.
Correction
Clean the area with one of the cleaners listed below.
Reseal the "A" pillar starting at the bottom of the weatherstrip retainer with the GM sealer listed below. Refer to the dotted line in the illustration for sealing.
Condition 5
Water is running down the front edge of the door or water is on top of the sill plate.
Cause
Water may be leaking around the weatherstrip at the top of the door due to an undesirable nub in the weatherstrip at the top of the door. Refer to the arrow in the illustration .
Two screws may not be sealed under the "A" pillar garnish molding. Refer to the illustration. During water test with the "A" pillar molding off, there may be water coming out of either the garnish molding retaining hole or the wire harness retaining hole. Refer to the arrow in the illustration.
Correction
Replace the weatherstrip.
Seal the two screws with the Kent™ sealer listed below.
