Honda Accord: Power Transistor Test
1. Remove the passenger's dashboard undercover (see page 20-170).
2. Disconnect the 4P connector from the power transistor.
3. Measure the resistance between terminals No. 3 and No. 4 of the power transistor. It should be about 1.5 kO.
• If the resistance is within the specifications, go to step 4.
• If the resistance is not within the specifications, replace the power transistor.
NOTE: Also check the blower motor. Power transistor failure can be caused by a defective blower motor.
POWER TRANSISTOR
4. Carefully release the lock tab on terminal No. 1 (PUR) (A) in the 4P connector, then remove the terminal and insulate it from body ground.
(To 12 V Power source on vehicle)
5. Reconnect the 4P connector to the power transistor.
6. Make sure the PUR wire is completely isolated, then supply 12 V to cavity No. 1 with a jumper wire.
7 Turn the ignition switch to ON (II), and check that the blower motor runs.
• If the blower motor does not run, replace the power transistor.
NOTE: A faulty blower motor can cause the power transistor to fail. If the power transistor is replaced, also check the blower motor for binding, and replace it if necessary.
• If the blower motor runs, the power transistor is OK.
Evaporator Temperature Sensor Test
NOTE: Before testing the sensor, check for HVAC DTCs
(see page 2 1 - 9).
