Dodge Repair: overflow, inlet air temperature sensor, carpet overview

Question
i have a 2003 geand caravan with the same overflow symptoms, the passenger carpet is soaked. I located the overflow tube inside the engine compartment, and tried unsuccessfully to wind a wire inside to free the clog. Is there a way to approach this from the interior of the van?

HVAC Drain Water (AC Condensate) Leaks Under Passenger Side Carpet
OVERVIEW:
This bulletin involves installing a HVAC drain tube O-ring.
MODELS:

NOTE: This bulletin applies to vehicles built on or before December 16, 2005 (MDH

SYMPTOM/CONDITION:
The customer may describe a wet front passenger floor or floor carpet. This condition may
be due to water (A/C condensate) from the HVAC assembly drain tube.
DIAGNOSIS:
Verify the passenger side front floor or carpet is wet. Check the source of the water leak.
As A/C condensate leaves the HVAC drain tube, it may run back along the outside of the
drain tube, past the seal, and under the passenger side front floor carpet. If the HVAC
assembly drain tube is the cause of the water leak, perform the Repair Procedure.
