Yes

>> Go to 2

No

>> Repair the Fused B(+) circuit for an open.

Perform BODY VERIFICATION TEST.

MEASURE DRIVER POWER SEAT SWITCH GROUND CIRCUIT RESISTANCE

Turn the ignition off.

Measure the resistance between ground and the Driver Power Seat
Switch Ground circuit.

Is the resistance below 5.0 ohms?

Yes

>> Replace the Driver Power Seat Switch. (Refer to 8 -
