2004 vibe , water leak=-

[jamesmetairie]

2004 vibe, about 189,000 miles. windshield replaced 8 years (??) ago. Vibe painted above pin stripe a few months ago. No rust anywhere on the vehicle.Suspect leak origination spot = the black plastic trim that sits in the rain gutter from the top corner of windshield , passenger side . It runs from near windshield to the forward most bracket of the roof rack mount. I noticed after the paint job the black plastic trim was loose at the forward edge near the windshield . I just tired to push it down hoping it would click into place.
Question = is it likely the paint guy popped that trim off during the prep work? If so how was the vehicle built ? Is there some type of clip that black plastic trim snaps into. I,m seeing just a little water on the head liner corner near the plastic pillar forward of the the passenger head .
Thanks for any advice. Jamesmetairie
