I just got an 02 trailblazer and when driving in the wind there seems
to be a lot of wind noise coming from the top of front doors.

When the doors are open all the way it looks like the welds are loose
on the firewall pillar.

1 could this be causing the windnoise?

2 does this need to be repaired?

I had the same problem, wind noise at the top of the doors! I took it back
about 5 times before I solved the problem myself, as the dealer did not
help. It went to a body shop 3 times and we all agreed the metal is weak
near the welds. I ended up putting an extra piece of rubber moulding around
the door. My welds looked like they were loose, but after checking real
good they appeared ok, might be a factory defect for 2002? I weld for a
living, and I did not test them other than a visual after grinding the paint
off, touched the paint up afterwards. I think the place where the welds are
the base metal is not strong enough and bends slightly warping the base
metal where it is welded, thus causing the problem of the wind noise. I
know of 3 other people in the same boat, and they used my trick to make it
work out for them.

Good luck, and hope you find your solution. If the welds appear loose, I
would get them welded again.

I'll probably try to get them rewelded if I can find someone to do it.

I thought of foam weatherstrip around the top of the doors but I'm
leary about putting more stress on the door.

Thanlks for the reply pigpen
