STAGE | CHECK | ACT | | 1 | Turn the ignition switch and check to see if 12 In pressure on contact (WB) terminal resistor. | Yes | Go to the next step. | | No | Check resistor. | | 2 | Check to see if 12V voltage on pin (LQ) switch of the basic fan. | Yes | Check the switch of the basic fan. | | No | Check the harness between the resistor and the switch of the basic fan. |
MAIN FAN MOTOR DOES NOT WORK with switch MAIN FAN IN POSITION 4.
STAGE | CHECK | ACT | | 1 | Turn the ignition switch and check to see if 12 In pressure on contact (WB) resistor. | Yes | Go to the next step. | | No | Check resistor. | | 2 | Check to see if the voltage at the 12 contact (LG) switch of the basic fan. | Yes | Check the switch of the basic fan. | | No | Check the harness between the resistor and the switch of the basic fan. |
CLOSED DRIVE CHANGE mode (not deflect the flow through the grille panel).
STAGE | CHECK | ACT | | 1 | Ignition switch: OFF. Disconnect the wiring harness from the control unit. | | - | | 2 | Check whether the drive is feeding 12 to the contacts in the contact list and D, as well as to see if the direction of his work in reverse when the polarity of the power supply. | | Yes | Go to step 4. | | No | Go to the next step. | | 3 | Disconnect and check the drive mode change. | Yes | Check the harness between the drives. | | No | Replace drive. | | 4 | Check the harness between the terminals G, C, A, H, F drive mode change and drive. | Yes | Check the control unit. | | No | Repair the wiring harness. |
Do not mix cold and warm air.
STAGE | CHECK | ACT | | 1 | Turn off the ignition switch and disconnect the wiring harness of the control unit. | | - | | 2 | Check whether the drive by connecting contact (D) and to the terminal (N) to 12 V. | | Yes | Go to step 4. | | No | Go to the next step. | | 3 | Remove the drive and complete the checkout. | Yes | Check the wiring between the drives. | | No | Replace drive. | | 4 | Check the resistance between the contacts (C) and (F) in positions MAX. COLD and MAX. HEAT. Then check whether the more than 5 ohms resistance in the difference between the positions of max. COLD and MAX. HEAT. | Yes | Repair the wiring. | | No | |
CLOSED VENT recirculation / fresh air.
STAGE | CHECK | ACT | | 1 | Turn off the ignition switch and disconnect the wiring harness of the control unit, | | - | | 2 | Serve. 12 a contact (A) and check the directions of the leaf by grounding contact (D) or (C) | | Yes | Go to step 4. | | No | Go to the next step. | | 3 | Remove and inspect the drive flap recycle / fresh air. | Yes | Check the harness between the drives. | | No | Replace drive. | | 4 | Check it with a serviceable control unit and, if it is working properly, replace the original control unit. | Yes | Check drive mixing. | | No | Repair the wiring harness. |
CLOSED compressor when the circuit breaker of the air conditioner.
STAGE | CHECK | ACT | | 1 | Check the fuse (15 A). | Yes | Go to the next step. | | No | Replace the fuse. | | 2 | Turn the ignition switch and check the voltage between the pin (E) of the air conditioner and the relay contact (E) connected to the wiring harness of the car. | Yes | Go to the next step. | | No | Repair the wiring harness.
