Rear Climate Controls

For diagnosis and testing of the rear climate control system,
Refer to: Climate Control System (412-00 Climate Control System - General Information, Diagnosis and Testing).

The rear climate control system operation is determined by the settings on the front HVAC control panel selection, FDIM or from the rear climate control panel, known as the rear non touch screen RHVAC control module or rear touch screen RACM. Messages are sent to the HVAC control module over the CAN. The non touch screen RHVAC control module communicates on the MS-CAN. The rear touch screen RACM communicates on the HS-CAN3. The rear climate control components are hard wired to the HVAC control module. Air is cooled and dehumidified by the rear A/C evaporator core only if the front (main) climate control system is operating in a mode that requires A/C compressor operation.

Vehicles equipped with a rear non touch screen RHVAC control module, the second row and rear (third row) climate controls are controlled as one climate zone. When the climate control settings are selected to heat or cool, both rows are changed as one climate zone.

Vehicles equipped with a rear touch screen RACM, the second row and rear (third row) climate controls are independently controlled as two separate climate zones. When the climate control settings are selected the two zones are heated or cooled as a climate control zone for the second row and a separate climate control zone for the rear (third row). Through a setting in the rear touch screen RACM, the two zones can also be linked together.

The command for warm or cold air to the rear non touch screen RHVAC control module or rear touch screen RACM may make a difference in the rear air delivery vents. The commands that are directly inputted from the RHVAC control module or rear touch screen RACM to the rear air delivery and temperature system may work better than the commands that are directly inputted from the front HVAC system.

For rear climate control access information through FDIM Sync™ 3 or the front HVAC control module refer to Owner's Literature.

  • Rear (third row) fan speed control
  • Rear (third row) linked with second row climate control

For illustrations and second climate control button operation information, refer to the Owner's Literature.

Control System Logic

The rear (third row) climate control can be controlled by either the main front HVAC controls or the center console controls. When a selection is made on the rear climate control panel, known as the rear non touch screen RHVAC control module or rear touch screen RACM, a message is sent to the HVAC control module over the CAN. The non touch screen RHVAC control module communicates on the MS-CAN. The rear touch screen RACM communicates on the HS-CAN3.

Vehicles equipped with a rear non touch screen RHVAC control module, the second row and rear (third row) climate controls are controlled as one climate zone. When the climate control settings are selected to heat or cool, both rows are changed as one climate zone.

Vehicles equipped with a rear touch screen RACM, the second row and rear (third row) climate controls are independently controlled as two separate climate zones. When the climate control settings are selected the two zones are heated or cooled as a climate control zone for the second row and a climate control zone for the rear (third row). Through a setting in the rear touch screen RACM, the two zones can also be linked together.

Air Handling

The rear climate control system has the following features:

  • The driver has primary control of the rear climate control system or can transfer control to the rear passenger control panel.
  • The rear blower motor recirculates the air inside the vehicle. Outside air is not available to the rear system.
  • The rear temperature door and the rear air distribution door are controlled by electric actuator motors.
  • Movement of the rear temperature control between cool and warm causes a corresponding movement of the rear temperature door to mix air flowing through and around the rear heater core.
  • Movement of the rear mode control between PANEL and FLOOR causes a corresponding movement of the rear air distribution door to direct airflow between the panel (upper side trim panel) registers and the floor duct.
  • Airflow is directed to the passengers through adjustable registers. The heater floor duct supplies air to a fixed register, which is integral to the side trim panel.

The HVAC control module sends a PWM signal to the rear blower motor speed control to control the blower speed. The rear blower motor speed control provides variable ground feed for the blower motor. A delay function provides a gradual increase or decrease in blower motor speed under all conditions.

Component Description

Component Description

Rear Air Discharge Temperature Sensors

There are 2 rear air discharge temperature sensors in the rear (third row) climate control system:

  • The rear footwell air discharge temperature sensor is located within the right rear quarter panel lower air duct.
  • The rear air discharge temperature sensor is located within the right rear quarter panel upper air duct.

The rear air discharge temperature sensors contain a thermistor and are inputs to the HVAC control module. The sensors vary their resistance with the temperature. As the temperature rises, the resistance falls. As the temperature falls, the resistance rises. The HVAC control module uses the sensor information to maintain the desired temperature of the passenger cabin air.

Rear Air Distribution Door Actuator

The rear air distribution door actuator is located within the right rear quarter panel by the D pillar. The rear air distribution door actuator moves the rear air distribution door on command from the HVAC control module based on input from either the front or rear climate controls.

The rear air distribution door actuator contains a reversible electric motor and potentiometer. The potentiometer allows the HVAC control module to monitor the position of the rear air distribution door. The potentiometer circuit consists of a 5-volt reference signal connected to one end of a variable resistor, and a signal ground connected to the other. A signal circuit is connected to a contact wiper, which is driven along the variable resistor by the actuator shaft. The signal to the HVAC control module from the contact wiper indicates the position of the rear air distribution door.

RACM

The rear touchscreen is used to adjust the rear (second and third row) climate control and other functions. It communicates these inputs over the HS-CAN3. For more information on the RACM,
Refer to: Information and Entertainment System - System Operation and Component Description (415-00 Information and Entertainment System - General Information, Description and Operation).

Rear Blower Motor

The rear blower motor is located in the right rear panel by the D pillar. The rear blower motor is a variable speed motor that pulls air from the vehicle interior and forces it through the rear climate control housing and the rear climate control air distribution ducts.

Rear Blower Motor Speed Control

The rear blower motor speed control is located in the right rear panel by the D pillar. The rear blower motor speed control is a solid-state switch that uses a PWM signal from the HVAC control module to determine the desired rear blower motor speed and varies the ground feed for the rear blower motor to control the speed. A delay function provides a gradual increase or decrease in rear blower motor speed under all conditions.

Rear Climate Control Housing

The rear climate control housing is located in the right rear panel by the D pillar. The rear climate control housing directs airflow from the rear blower motor through the rear evaporator core and rear heater core. All airflow from the rear blower motor passes through the rear evaporator core. The airflow is then distributed to the selected outlet by the airflow mode doors.

Rear Evaporator

The rear evaporator core is an aluminum plate-and-fin type heat exchanger and is located in the rear climate control housing. A mixture of liquid refrigerant and oil enters the rear evaporator core through the rear evaporator core inlet tube and continues out of the rear evaporator core through the rear evaporator core outlet tube as a vapor. During A/C compressor operation, airflow from the rear blower motor is cooled and dehumidified as it flows through the rear evaporator core fins.

Rear Heater Core

The rear heater core consists of fins and tubes arranged to extract heat from the engine coolant and transfer the heat to air passing through the rear climate control housing.

Rear A/C - Heater Inlet and Outlet Lines

The rear climate control system A/C and heater inlet and outlet lines that are all part of an assembly that runs from front to back on the vehicle and are bracketed together and fastened to the underbody of the vehicle.

RHVAC Control Module

The rear non touch screen RHVAC control module is used by the rear vehicle occupants to request changes to the rear climate control system (second and third row). The requests are sent to the HVAC control module over the MS-CAN.

Rear Temperature Door Actuator

The rear temperature door actuator is located within the right rear quarter panel by the D pillar. The rear temperature door actuator moves the rear temperature door on command from the HVAC control module based on input from either the front or rear climate controls.

The rear temperature door actuator contains a reversible electric motor and potentiometer. The potentiometer allows the HVAC control module to monitor the position of the rear temperature door. The potentiometer circuit consists of a 5-volt reference signal connected to one end of a variable resistor, and a signal ground connected to the other. A signal circuit is connected to a contact wiper, which is driven along the variable resistor by the actuator shaft. The signal to the HVAC control module from the contact wiper indicates the position of the rear temperature door.

Rear temperature sensor - vehicles with: second row seats

The rear temperature sensor - vehicles with: second row seats is located in the headliner above the second row seating in the microphone bezel assembly. The rear temperature sensor contains a thermistor which separately measures the in-vehicle air temperature, then sends those readings to the HVAC control module. The HVAC control module may adjust the rear climate control system based on the second row seat rear temperature sensor information to maintain the desired temperature of the rear passenger cabin air.

Rear temperature sensor - vehicles with: third row seats

The rear temperature sensor - vehicles with: third row seats is located in the headliner above the third row seating in the microphone bezel assembly. The rear temperature sensor contains a thermistor which separately measures the in-vehicle air temperature, then sends those readings to the HVAC control module. The HVAC control module may adjust the rear climate control system based on the third row seat rear temperature sensor information to maintain the desired temperature of the rear passenger cabin air.

Rear Thermostatic Expansion Valve (TXV)

The rear Thermostatic Expansion Valve (TXV) is located at the rear evaporator core inlet and outlet tubes. The rear Thermostatic Expansion Valve (TXV) provides a restriction to the flow of refrigerant and separates the low-pressure and high-pressure sides of the rear refrigerant system. Refrigerant entering and exiting the rear evaporator core passes through the rear Thermostatic Expansion Valve (TXV) through 2 separate flow paths. An internal temperature sensing bulb senses the temperature of the refrigerant flowing out of the rear evaporator core and adjusts an internal pin-type valve to meter the refrigerant flow into the rear evaporator core. The internal pin-type valve decreases the amount of refrigerant entering the rear evaporator core at lower temperatures and increases the amount of refrigerant entering the rear evaporator core at higher temperatures.
