Power Transistor Test
1. Disconnect the 5P connector from the power
transistor.
2. Measure the resistance between the No. 1 and
No. 4 terminals of the power transistor. It should be
approximately 1.4 1.5 k .
• 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. 3 terminal
(ORN/BLK) (A) in the 5P connector, then remove the
terminal and insulate it from body ground.

4. Connect a 1.2 3.4 W bulb (B) between the No. 3
and the No. 4 cavity on the 5P connector.
5. Reconnect the 5P connector to the power transistor.
6. Turn the ignition switch ON (II), and check that the
blower motor runs.
• If the blower motor does not run, replace the
