SYMPTOM/CONDITION:
The customer may experience a wet front passenger floor or floor carpet. This condition may occur due to water (NC 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 HVAC drain tube1 enter the passenger compartment, and run under the front floor carpet on the passenger side. This condition occur most often while the vehicle is being driven.
DIAGNOSIS:
Inspect for the source of the water leak. Determine if the passenger side of the front floor carpet is wet because of air conditioning condensate from the HVAC drain tube. Inspect the HVAC assembly drain tube for the presence of a drain hose. If a HVAC assembly drain hose is not present and the NC condensate from the drain tube is the cause of the water leak, perform the Repair Procedure.
PARTS REQUIRED:
REPAIR PROCEDURE:
