VF Odometer Inoperative With Door Open

Possible Causes:

• Defective Fuse
• Door Ajar Sense Circuit Short To Voltage
• Ajar Switch
• Door Ajar Switch Sense Circuit Open
• Door Ajar Switch Ground Circuit Open
• Instrument Cluster

Testing

1. Turn ignition off. Check fuse No. 4 (10-amp) in fuse block, located on firewall next to glove box. If fuse is faulty, go to next step. If fuse is okay, go to step  3 .
2. Turn ignition off. Remove instrument cluster. See INSTRUMENT CLUSTER  under REMOVAL & INSTALLATION. Check voltage between instrument cluster harness connector C2 terminal No. 3 (Tan/Yellow wire) and ground (driver's door ajar switch circuit). See Figure . Check voltage between instrument cluster harness connector C2 terminal No. 4 (Tan wire) and ground (passenger's door ajar switch circuit). If voltage does not exist, go to next step. If voltage exists, repair short to voltage on affected circuit.
3. Disconnect driver's or passenger's door ajar switch. Connect a jumper wire between door ajar switch harness connector terminals No. 1 and 3. If VF odometer does not illuminate, go to next step. If VF odometer illuminates, replace door ajar switch.
4. Remove jumper wire. Connect jumper wire between door ajar switch harness connector terminal No. 3 (Tan/Yellow or Tan wire) and ground. See Figure . If VF odometer illuminates, go to next step. If VF odometer does not illuminate, repair open circuit between door ajar switch and instrument cluster.
5. Check resistance between driver's or passenger's door ajar switch harness connector terminal No. 1 (Tan/Black wire) and ground. See Figure . If resistance is 5 ohms or more, repair open in Yellow/Black wire or Black wire to ground. If resistance is less than 5 ohms, replace instrument cluster. See INSTRUMENT CLUSTER  under REMOVAL & INSTALLATION.
