Removal and installation
1. Remove the mounting block in the passenger compartment.
2. Disconnect the connector (A) from the air mixing actuator (B).
Example of code output "3"
3. Loosen the screws and remove the drive.
4. Disconnect the rod (C).
5. Install in the reverse order of removal.
6. Make sure the drive operates smoothly.
Examination
1. Disconnect the connector from the air mixing actuator.
2. Connect the battery to terminals "1" (+) and "2" (-), make sure the throttle moves to the "MAX COOL" position. Reverse the polarity and make sure the throttle moves to the "MAX HOT" position.
If the air mixing actuator does not work, replace it.
Air conditioning system diagnostics (automatic air conditioner).
| Code | Component being diagnosed | Possible cause of the malfunction |
| 1 | Cabin air temperature sensor | - Broken wiring - Malfunction of the air temperature sensor in the cabin |
| 2 | Cabin air temperature sensor | - Short circuit in wiring - Malfunction of the air temperature sensor in the cabin |
| 3 | Outside air temperature sensor | - Broken wiring - Malfunction of the outside air temperature sensor |
| 4 | Outside air temperature sensor | - Short circuit in wiring - Malfunction of outside air temperature sensor |
| 5 | Sunlight sensor | - Broken wiring - Malfunction of the sun sensor |
| 6 | Sunlight sensor | - Short circuit in wiring - Malfunction of sun sensor |
| 7 | Air flow mixing drive | Broken wiring |
| 8 | Air flow mixing drive | Short circuit in wiring |
| 9 | Air flow mixing drive | Electric motor jamming |
| 10 | Air flow direction change drive | Open or short circuit in wiring |
| 11 | Air flow direction change drive | Electric motor jamming |
| 12 | Heater fan | - Fuse - Wiring break or short circuit - Electric motor jammed |
| 13 | Air conditioning and heating control unit | Internal error |
| 14 | Evaporator Air Temperature Sensor | - Broken wiring - Malfunction of the air temperature sensor behind the evaporator |
| 15 | Evaporator Air Temperature Sensor | - Short circuit in wiring - Malfunction of the air temperature sensor behind the evaporator |
If the actuator operates unevenly, make sure the damper and rod move evenly.
If the damper and rod move evenly, replace the air mixing actuator.
If the damper and rod do not move evenly, repair them.
3. Measure the resistance between terminals "4" and "5".
Resistance - 2.1-3.9 kOhm
4. Measure the resistance between terminals "3" and "4".
Resistance:
- MAX NOTE - 1.56-3.24 kOhm
- MAX COOL — 0.35 - 0.91 kOhm
