b. Rear floor mat support plate
c. Quarter trim panel RH




REMOVE POWER TRANSISTOR
a. Disconnect the connector.
b. Remove the 2 screws and blower resistor.




INSPECT POWER TRANSISTOR OPERATION
a. Connect the positive (+) lead to terminal 1 through a 12 V - 3.4 W test bulb and negative (-) lead to terminal 2.
b. Check the test bulb lights up when another positive (+) lead is connected to terminal 4 through a 12 V - 3.4 W test bulb.
If operation is not as specified, replace the power transistor.




INSPECT POWER TRANSISTOR RESISTANCE
Measure resistance between terminals 3 and 4.
Standard resistance: 2.0-2.4 K Ohms
If resistance is not as specified, replace the power transistor.

INSTALL POWER TRANSISTOR
