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
- Disconnect the blower power transistor connector.
- 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.
- Reconnect the connector to the blower power transistor.
- Connect climate control unit connector A (32P) terminals No. 2 and No. 4
with a
jumper wire
- Turn the vehicle to the ON mode
- 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
- Install the parts in the reverse order of removal.
BLOWER RESISTOR 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 Resistor - Test
- Disconnect the blower resistor connector.
- Measure the resistance between the following terminals of
the blower resistor and compare them with the values in the
table.
NOTE: Also check the blower motor. Blower resistor failure
can be caused by a defective blower motor.
- If the resistance is not within the specifications, replace the
blower resistor.
3. All Removed Parts - Install
- Install the parts in the reverse order of removal.

1. Radiator Cap - Remove
Wait until the engine is cool, then carefully remove the radiator cap.
2. Engine Undercover - Remove (With Engine Undercover)
3. Engine Coolant - Drain
Loosen the drain plug (A), and drain the coolant
After the coolant has drained, tighten the radiator dra
