Certain vehicles fail to conform to Canada Motor Vehicle Safety Standard 103 - Windshield Defrosting and Defogging. Software in the Electronic Climate Control (ECC) module may disable the ability to adjust the Heating, Ventilation, and Air Conditioning (HVAC) system settings. If this happens, the driver will not be able to control the heating, cooling, and ventilation of the vehicle. Loss of windshield defrosting and defogging function may, under certain driving conditions, compromise the driver's ability to see the road and its users, which could result in a crash causing property damage and/or personal injury.
On certain vehicles, the interface between the electrical terminals of the Heating, Ventilation, and Air Conditioning (HVAC) blower relay resistor module and the wiring connector (which powers the module) may be incapable of conducting higher current levels for sustained periods of operation. In addition, moisture and other contaminants (such as road de-icing materials) may enter the fresh air intake plenum and contact the internal circuit of the module or corrode the terminals. These conditions may cause the relay resistor module or wiring connector to overheat, causing various symptoms such as: the HVAC blower may not function on certain or all blower speed settings; a burning-plastic smell or smoke may be present in the vehicle, or; the HVAC blower may run continually with the ignition in the OFF position. These warning signs could, in certain instances, be leading indicators of an impending vehicle fire, which could result in property damage and/or personal injury.
Safety Risk
No risk description available.
Remedy
Owners will be provided with additional warranty coverage for the blower motor resistor module/wiring connector overheating condition. Under this "special warranty coverage", should this condition occur within 10 years or 240,000 km from first vehicle registration, dealers will install a replacement blower motor resistor and resistor module connector.
On certain vehicles, the software programming in the Heating, Ventilation, Air Conditioning (HVAC) controller may allow a combination of numerous data inputs to temporarily overload the calculation capacity of the controller, resulting in incorrect signals to be transmitted to the heater case mode door. This may cause the mode door to move to unselected positions during heater operation until the controller recovers and returns to proper operation. Over time, this excessive movement may damage the mode door shaft. These conditions could affect defroster performance, resulting in delayed clearing of the windshield, which could compromise safe vehicle operation and increase the risk of a crash.
Safety Risk
No risk description available.
Remedy
Dealers will replace the HVAC controller assembly, inspect the mode-door shaft for possible damage, and repair the mode-door shaft if necessary.
Certain vehicles were built with heating, ventilation, and air conditioning (HVAC) control knobs that may fracture and spin on the control shaft. If this happens, the driver may no longer be able to control the heating, cooling, and ventilation for the vehicle. This may affect the defrost system, decreasing driver visibility, and creating the risk of a crash causing property damage, personal injury or death.
On certain vehicles, the software in the Integrated Center Stack can cause the heating, air conditioning, defrost, the radio controls, and the panel illumination to become inoperative. Driving without some of these functions could increase the risk of a crash causing property damage, personal injury or death.
On certain vehicles equipped with manual temperature control, the software programmed into the heating, ventilation and air conditioning (HVAC) module may cause the windshield defrosting and defogging functions to become inoperative. This may decrease the driver's visibility under certain driving conditions and result in a vehicle crash causing property damage, personal injury or death.
On certain vehicles, the Climate Control Module may receive a "Shut-down signal" from the Engine Control Module (ECM) after ignition key insertion. If this condition occurs, the climate control functions will not be available (including defroster) during that driving cycle. This can decrease the driver's visibility under certain driving conditions and cause a crash with personal injury or death.
