2003 Impala - Driver's Side Water Leak

[mp1642]

I have a water leak from the driver's side on my 2003 Impala ( hard to believe but its not comming from passenger side ( fixed the loose cowl seal for cabin filter area last year )

I have removed the plastic trim from the knee bolster panels, kick plate, fuse panel and A-pillar. I can see water dripping down near the fuse block area to the floor. I followed it up to the top of the A-pillar near headliner and windshield area. I had a crack in the windshield ( unrelated ), and asked the glass guy if the drivers top corner of the glass was not sealed. He removed the old glass and had me inspect with him. He indicated that all looked good and could not find any indicator that would cause water leak.

Anybody with same problem that has an idea where this may be comming from ????

could check where the cowl and firewall come together, or in the cowl where the air intake for the ventelation comes in. i work in sealer in a nissan assembly plant, so not too familiar with the newer gm cars. hope ive helped.

Thanks for the reply but unfortunately I traced the leak to the top of the drivers side A-pillar and windshield/ headliner. I suppose next step is to drop headliner asm.

UPDATE !!!

Traced leak to windshield/ body pinch weld. Added additional urathane to inside and outside portion of windshield and body.
Had plenty of rain in the past few weeks and no more leaks!!!

finally an answer! i have been trying to find this leak for almost a year. ive taken apart the dash and outside cowling but couldnt find it.

i have questions though:

what is a pinch weld
do you have a pic of the pinch weld?

can you describe it to me if you dont have a pic so i know what i am looking for?

is th urethane stuff you used that orange goop that they use for like gaskets and stuff?

i know i am asking a lot but i dont know too much about working from the interiors

any help would be great thanks!

pinchweld i think is where like inside panel is folded and pinched to outside body panel, urethane is black bonding material that goes around windshield and frame to prevent leaks all of this of course is just my assumption
thanks
