3.
Verify that the temperature control actuator operates to the hot position when connecting 12V to the terminal 4 and grounding terminal 3.
Verify that the temperature control actuator operates to the cool position when connecting in the reverse.
Ignition "OFF"
Disconnect the connector of temperature control actuator.
Verify that the temperature control actuator operates to the hot position when connecting 12V to the terminal 4 and grounding terminal 3.
Verify that the temperature control actuator operates to the cool position when connecting in the reverse.
Check the voltage between terminals 6 and 7.
Door position | Voltage (6-7) | Error detecting |
Max. cooling | 0.3 ± 0.15V | Low voltage : 0.1V or less |
Max. heating | 4.7 ± 0.15V | High voltage : 4.9V or more |
It will feedback current position of actuator to controls.
If the measured voltage is not specification, substitute with a known-good temperature control actuator and check for proper operation.
If the problem is corrected, replace the temperature control actuator.
Disconnect the negative (-) battery terminal.
Remove the crush pad lower panel (A).
Remove the glove box (A).
Remove the crash pad lower panel(A).
Remove the sower duct(A).
Disconnect the temperature control actuator connector (A).
Loosen the mounting screw and then remove the temperature control actuator (B).
Installation is the reverse order of removal.
