Is the resistance between 240K and 400K ohms?
Yes | GO to AB31 |
|---|---|
No | GO to AB30 |
AB30 CHECK THE BLOWER SPEED CONTROL RESISTANCE
Disconnect: Driver Seat Backrest Blower Motor C3034.
NOTE: The ohmmeter must be connected with the positive lead to pin 7 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:
Positive Lead | Measurement / Action | Negative Lead |
|---|---|---|
C3034-7, Component Side | C3034-4, Component Side |
Is the resistance between 240K and 400K ohms?
Yes | REPAIR the circuit(s) in question. GO to AB36 |
|---|---|
No | INSTALL a new backrest blower motor. REFER to: Front Seat Backrest Blower Motor (501-10 Front Seats) . GO to AB36 |
AB31 CHECK THERMISTOR CIRCUIT FOR A SHORT TO VOLTAGE

Is any voltage present?
Yes | REPAIR the circuit. GO to AB36 |
|---|---|
No | GO to AB32 |
AB32 CHECK THERMISTOR CIRCUIT FOR A SHORT TO GROUND
REFER to: Supplemental Restraint System (SRS) Depowering (501-20B Supplemental Restraint System, General Procedures). Disconnect: Driver Side Airbag In-line C345. Disconnect: Passenger Side Airbag In-line C219. Disconnect: SCME C3265B. Measure:
