If Spot Lamp Does Not Light

  1. If both spot lamps are inoperative, check spot lamp master fuse. Refer to appropriate Wiring Diagrams for fuse locations. If fuse is OK, go to Step  4. If fuse is damaged or inoperative, replace as necessary.
  2. If the left spot lamp is inoperative, check fuse. If fuse is OK, go to Step  4. If fuse is damaged or inoperative, replace as necessary. If fuse blows again, find short to ground. Refer to Wiring Diagrams for circuit information.
  3. If the right spot lamp is inoperative, check fuse. If fuse is OK, go to Step 4. If fuse is damaged or inoperative, replace as necessary. If fuse blows again, find short to ground. Refer to Wiring Diagrams for circuit information.
  4. Check for B+ power at the spot lamp bulb with switch turned ON. See Diagnosis and Testing . If there is B+ power at the spot lamp bulb connector, replace bulb. If there is not B+ power present, go to Step 5.
  5. If there is not B+ power present at the spot lamp with the switch turned on, check circuit for an open. Possibly the connector in the A-pillar. Refer to Wiring Diagrams for circuit information.
  6. If there is B+ power at the spot lamp connector, and no B+ power at the spot lamp bulb, then the switch is damaged or inoperative within the spot lamp assembly and the entire unit must be replaced. See Electrical - Lamps and Lighting/Lamps/Lighting - Exterior/LAMP, Spot - Removal .
  7. If lamp still does not light, remove the handle. See Electrical - Lamps and Lighting/Lamps/Lighting - Exterior/LAMP, Spot - Removal , and check the contact on the shaft end of the head assembly into the handle to make sure the contact is not damaged.
