2007 > 2.7L V6 GASOLINE >
INSPECTION
1.Ignition "ON"
2. Manually operate the control switch and measure the voltage of blower motor between pin 1 and 2.
3. Select the control switch to raise voltage until high speed.
Specification
Fan Motor Voltage
Manual
First speed 4.0 ±0.5V
Second speed 5.1 ±0.5V
Third speed 6.2 ±0.5V
Fourth speed 7.3 ±0.5V
Fifth speed 8.4 ±0.5V
Sixth speed 9.5 ±0.5V
Seventh speed 10.5 ±0.5V
eighth speed Battary(+)
*AUTO COOLING: Auto speed (4.5V~B+)
*AUTO HEATING: Auto speed (4.5V~10.5V)
4. If the measured voltage is not specification, substitute with a known- good power mosfet and check for proper
operation.
5. If the problem is corrected, replace the power mosfet.
REPLACEMENT
1.Disconnect the negative ( - ) battery terminal.
2. Disconnect the power mosfet connector (A) at the connecting part between heater and blower unit.
3. Remove the power mosfet (B) after loosening the mounting screws.

DESCRIPTION
1.The intake actuator is located at the blower unit.
2. It regulates the intake door by signal from control unit.
3. Pressing the intake selection switch will shift between recirculation and fresh air modes.

2007 > 2.7L V6 GASOLINE >
INSPECTION
1.Ignition "OFF"
2. Disconnect the intake actuator connector.
3. Verify that the actuator operates to the recirculation position when connecting 12V to the terminal 3 and grounding
terminal 4.
4. Verify that the intake actuator operates to the fresh position when connecting in the reverse.
5.If the intake actuator is not operated well, substitute with a known- good intake actuator and check for proper
operation.
6. If the problem is corrected, replace the intake actuator.
REPLACEMENT
1.Disconnect the negative ( - ) battery terminal.
2. Remove the glove box (Refer to BD group).
3. Disconnect the intake actuator connector.
4. Loosen the mounting screw and then remove the intake actuator (A) from the blower unit.
5.Installation is the reverse order of removal.
