Front Seats — 2016 workshop reference 1084

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

Yes	GO to AC29
No	GO to AC28

AC28 CHECK THE BLOWER RESISTANCE

Disconnect: Passenger Seat Backrest Blower Motor C3039.

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:
