Power Transistor HVAC: Testing and Inspection

1. Pull out the No. 2 (ORN/BLK) terminal from the power transistor 3P connector, then connect a 1.2 - 3.4 W bulb between the No. 1 cavity and the No. 2 cavity as shown.
2. Turn the ignition switch ON (II), and check that the blower motor runs.

CAUTION:
- To avoid a loose or disconnected terminal, be careful not to damage the locking tab when disconnecting and connecting the terminal.
- Insulate the No. 2 (ORN/BLK) terminal from the body until the testing is completed.
