Problem?

Well, the main issue may be that your drip lines are clogged. However,
in very humid situations, with a very good working AC unit, it can be
that your whole system is causing the moisture to condense.

Access to the drip lines can be tricky. Presuming this is a passenger
van, you may be able to access them from the D pillar openings on the
outside.

Under normal circumstances, there is a drip tray under the evaporator
portion of your AC (that portion that is in the rear above the cargo
area) The drip tray has rubber tubes that feed into the D pillars and
allow condensation to drip outside. Those tubes could be clogged, or
(if your AC has been worked on) they could be kinked, or even not
inserted properly so as to prevent the condensation (water) from going
outside.

And you could have a nice puddle of water in your drip tray as a result.

Lowering the plastic housing that holds the evaporator can gain you
access to the rubber tubes. Be careful as the evaporator is fairly
heavy. To lower it, you will need to remove the 6 bolts on the front
of the housing and the plastic housings covering the D pillar. You
might try only removing one side and lower it a bit to gain access.
