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.

As A/C condensate leaves the HVAC drain tube, it may run back along the outside of the

assembly drain tube is the cause of the water leak, perform the Repair Procedure.
