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.

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.
