CUSTOMER SATISFACTION PROGRAM
SUBJECT:

HVAC Drain Tube Misalignment

MODELS:

2014 Chevrolet SS
2014 Chevrolet PPV
THIS PROGRAM IS IN EFFECT UNTIL JULY 31, 2016.

CONDITION
Certain 2014 model year Chevrolet SS and Caprice PPV vehicles may have a condition in which
the HVAC drain tube spigot, at the base of the instrument panel, is incorrectly aligned to the elbow
port on the center tunnel. If this condition is present, a leak may occur and vehicle occupants may
notice wet floor carpet, most likely beginning in either the left or right front foot wells.
CORRECTION
Dealers are to install a rubber grommet in the drain duct housing.
VEHICLES INVOLVED
All involved vehicles are identified by Vehicle Identification Number on the Investigate Vehicle
History screen in GM Global Warranty Management system. Dealership service personnel should
always check this site to confirm vehicle involvement prior to beginning any required inspections
and/or repairs. It is important to routinely use this tool to verify eligibility because not all similar
vehicles may be involved regardless of description or option content.
For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle
identification number, customer name, and address information has been prepared and will be
provided to U.S. dealers through the GM GlobalConnect Recall Reports. Dealers will not have a
report available if they have no involved vehicles currently assigned.
The listing may contain customer names and addresses obtained from Motor Vehicle Registration
Records. The use of such motor vehicle registration data for any purpose other than follow-up
necessary to complete this program is a violation of law in several hastates/provinces/countries.
Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete
this program.

CUSTOMER NOTIFICATION
General Motors will notify customers of this program on their vehicle (see copy of customer letter
included with this bulletin).
DEALER PROGRAM RESPONSIBILITY
All unsold new vehicles in dealers' possession and subject to this program must be held and
inspected/repaired per the service procedure of this program bulletin before customers take
possession of these vehicles. Dealers are to service all vehicles subject to this program at no
charge to customers, regardless of mileage, age of vehicle, or ownership, through June 30th,
2016.
Customers who have recently purchased vehicles sold from your vehicle inventory, and for which
there is no customer information indicated on the involved vehicle listing, are to be contacted by
the dealer. Arrangements are to be made to make the required correction according to the
instructions contained in this bulletin. A copy of the customer letter is provided in this bulletin for
your use in contacting customers. Program follow-up cards should not be used for this purpose,
since the customer may not as yet have received the notification letter.
In summary, whenever a vehicle subject to this program enters your vehicle inventory, or is in your
facility for service through July 31, 2016, you must take the steps necessary to be sure the program
correction has been made before selling or releasing the vehicle.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that
may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the tools,
equipment, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to
your vehicle, or that your vehicle will have that condition. See your dealer for information on whether your vehicle may benefit from the information.
