C3265C-12		Ground

Are the resistances greater than 10,000 ohms?

Yes	GO to AB27
No	REPAIR the circuit in question. GO to AB36

AB27 CHECK THE BLOWER AND WIRING RESISTANCE

NOTE: The ohmmeter must be connected with the positive lead to pin 16 and the negative lead to pin 15 when measuring. Ohmmeter leads incorrectly connected will result in false readings and lead to incorrect identification of components that are not faulty. Measure:

Is the resistance between 4,000 and 10,000 ohms?

Yes	GO to AB29
No	GO to AB28

AB28 CHECK THE BLOWER RESISTANCE

Disconnect: Driver Seat Backrest Blower Motor C3034.

NOTE: The ohmmeter must be connected with the positive lead to pin 3 and the negative lead to pin 4 when measuring. Ohmmeter leads incorrectly connected results in false readings and leads to incorrect identification of components that are not damaged. Measure the component side resistance between:
