Repair Procedures

Inspection

1. 1
   Turn the ignition on.
2. 2
   Manually operate the control switch and measure the blower motor voltage.
3. 3
   Select the control switch to raise the voltage until it reaches the high speed.

   

   Specification

   Fan	Blower Motor Voltage
   	Manual
   First Speed	3.8 ± 0.5 V
   Second Speed	5.0 ± 0.5 V
   Third Speed	6.2 ± 0.5 V
   Fourth Speed	7.4 ± 0.5 V
   Fifth Speed	8.6 ± 0.5 V
   Sixth Speed	9.8 ± 0.5 V
   7th Speed	11.0 ± 0.5 V
   8th Speed	Battery (+)

4. 4
   If the measured voltage does not meet the specification, replace the power MOSFET with a known good one and check operation.
5. 5
   Replace the power MOSFET if it is confirmed to be faulty.

Replacement

1. 1
   Disconnect the negative (-) battery terminal.
2. 2
   Remove the luggage side trim (Refer to Body - Luggage Side Trim).
3. 3
   Disconnect the rear blower motor connector (A) and the rear power MOSFET connector (B). Loosen the mounting screws and remove the rear power MOSFET (C).

   

4. 4
   Install in the reverse order of removal.

   Make sure the connector is properly connected.
