Examination
1. Disconnect the 5-pin connector from the power transistor.
2. Measure the resistance between contacts No.1 and No.3 of the transistor.
- Standard resistance: 1.5kΩ ±1%
3. Remove contact #3 (blue/yellow wire) from the connector and reconnect the connector to the power transistor.
Attention.
- Do not damage the contact.
- Do not allow the removed contact to come into contact with other parts.
4. As shown in the figure, connect the (+) wire from the battery to terminal #3 of the connector, and the (-) wire to terminal #5.
5. Turn the ignition key to the ON (II) position and make sure the blower motor is running.
