Power Transistor Test

Power Transistor Test

1. Disconnect the 4P connector from the power transistor.




2. Measure the resistance between the No. 1 and No. 3 terminals of the power transistor. It should be about 1.5 k ohm.
- If the resistance is within the specifications, Go to step 3.
- If the resistance is not within the specifications, replace the power transistor.




3. Carefully release the lock tab on the No. 2 terminal (BLU/YEL) (A) in the 4P connector, then remove the terminal and insulate it from body ground.
4. Reconnect the 4P connector to the power transistor.
5. Make sure the BLU/YEL wire is completely isolated, then supply 12 V to the No. 2 cavity with a jumper wire.
6. Turn the ignition switch ON (II), and check that the blower motor runs.
- If the blower motor does not run, replace the power transistor.
- If the blower motor runs, the power transistor is OK.
