Honda HR-V: Blower Power Transistor Test

Test

SRS components are located in this area. Review the SRS component locations - Refer to: SRS Component Location Index (KA/KC), or SRS Component Location Index (KA/KC) and the precautions and procedures before doing repairs or service.

1. Glove Box - Remove

2. Blower Power Transistor - Test

HVAC System - Testing & Troubleshooting

  1. Disconnect the blower power transistor connector.
  2. Measure the resistance between terminals No. 1 and No. 3 of the blower power transistor. It should be about 1.5 kΩ.
    • If the resistance is within the specifications, go to step 3.
    • If the resistance is not within the specifications, replace the blower power transistor.

    NOTE: Also check the blower motor. Blower power transistor failure can be caused by a defective blower motor.

  3. Reconnect the connector to the blower power transistor.

HVAC System - Testing & Troubleshooting

  1. Connect climate control unit connector A (32P) terminals No. 2 and No. 4 with a jumper wire
  2. Turn the vehicle to the ON mode
  3. Check that the blower motor runs.
    • If the blower motor does not run, replace the blower power transistor.

    NOTE: A faulty blower motor can cause the blower power transistor to fail.

    Before replacing the blower power transistor, check the blower motor for binding, and replace it if necessary.

    • If the blower motor runs, the blower power transistor is OK.

3. All Removed Parts - Install

  1. Install the parts in the reverse order of removal.
