Most likely it’s the drains
There are some rubber tubes that drain from around the sunroof down Thru the A pillar Thru the kick panel and out right behind the front wheel
It’s a pain to blow em out or run some weed eater line Thru them
But it doesn’t cost anything
My expedition used to do that
Till we cleaned em out
Also on our expy if you parked it where the front was uphill it didn’t leak so we did that till I got time to clean em out
