Service VME - Passenger Floor Carpet Wet - hose HVAC leakmodule moisture pan right side sunroof top water

When servicing the vehicle with the VIN you entered, the following diagnosis might be helpful if the vehicle exhibits the described symptoms.

Should a customer indicate that the passenger side floor carpet is wet, the most probable cause is that water is finding its way from the plenum area into the HVAC module through an opening at the top referred to as the chimney. The source of the water is the R/H sunroof drain hose. Reposition the hose or extend it to redirect the water away from the opening in the HVAC module.

A bulletin and service kit will soon be made available.

Please follow this diagnosis process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed. If these steps do not resolve the condition, please contact GM TAC for further diagnostic assistance. This diagnostic approach was developed for the vehicle with the VIN you entered and should not be automatically be used for other vehicles with similar symptoms.
