Jeep Repair: 2003 Liberty water in passenger floor, caravan voyager, cherokee international

Question
I have water coming in somewhere on the passenger's side. I check the air drain and it is open and has a seal where it goes through the firewall. It is definitely water and not antifreeze.  It seems worse in the back seat floor but it could be running to the back from the front. Unfortunatly it just started raining from a summer of no rain and we just noticed it and can't tell if it from the air or rain. Any ideas where to start.

Passenger Compartment Floor Water Leak
OVERVIEW:
This bulletin involves sealing the opening for the evaporator hose/drain tube with RTV
sealer.

SYMPTOM/CONDITION:
Water may enter the passenger compartment between the HVAC housing and the
bulkhead. A foam seal is used to seal the heater housing to the bulkhead. Condensation
from the A/C evaporator can run along the evaporator drain tube and enter the passenger
compartment if the seal between the HVAC housing and the bulkhead is not sealed
properly. This will result in wet passenger compartment carpet when the air conditioning is
operating.

If the symptom exists, perform the Repair Procedure.
