Driver's Switch

  1. Turn ignition on. Using an analog voltmeter, backprobe driver's seat switch connector. Battery voltage should exist between terminals No. 1 (Yellow wire) and No. 4 (Black wire). If battery voltage does not exist, repair Yellow wire to fuse panel, or Black wire to ground.
  2. Operate any driver's seat control switch. Backprobe terminal No. 3. If meter does not indicate approximately 1.0-1.6 volts, switch is defective. Repeat step 2) for each switch position.
  3. Release switch. Backprobe terminal No. 3. If meter does not indicate approximately zero volts, switch is defective.
