its the sunroof. how do i fix leaking sunroof?
there are three ways I've done the 1st one w/o spending arms n legs so its really up to the owner, here it goes.

1. go to home depo find a water proof tape and tape all around the sunroof gasket line ,dry the roof top 1st b4 application.

2. order a sunroof gasket w/ instructions. and follow the instruction kit.

3. follow#1

Is that a factory sunroof?
On my 93, the sunroof drains back through the rear roof pillars through the trunk and exit behind the rear wheels. Blow compressed air through hose. Check for leaves or crap that cause blockages.
The insulating tape trick is good too for squeaky sunroof.
