Front Seats — 2016 workshop reference 1079

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

Yes	GO to AC14
No	GO to AC13

AC13 CHECK THE BLOWER RESISTANCE

Disconnect: Passenger Seat Cushion Blower Motor C3040.

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:

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

Yes	REPAIR the circuit in question. GO to AC36
No	INSTALL a new passenger seat cushion blower motor. REFER to: Front Seat Cushion Blower Motor (501-10A Front Seats, Removal and Installation). GO to AC36

AC14 CHECK THE BLOWER SPEED CONTROL AND CIRCUIT RESISTANCE

NOTE: The ohmmeter must be connected with the positive lead to pin 3 and the negative lead to pin 7 when measuring. Ohmmeter leads incorrectly connected results in false readings and leads to incorrect identification of components that are not damaged. Measure:
