Troubleshooting Hints - Exterior Lights

1. If the Turn Lights or Backup Lights do not work, check Fuse 18. If open, check for short to ground in CKT 75.
2. If the Stop Lights or Hazard Lights do now work, check Fuse 19. If open, check for short to ground in CKT 140.
3. If one of the Turn Indicators goes on when the Park Lights are turned on, check the Front Park/Turn Lamp on that side for open or poor connection.
4. If Turn Lights stay on (do not flash) in both Turn Left and Turn Right, replace the Turn Flasher.
5. For any of the following symptoms, replace the Turn/Hazard Switch Assembly:
^ Turn Signal Switch will not turn "ON"/"OFF".
^ All Turn/Hazard/Stop Lights do not work and C210 is firmly mated.
^ Some Turn Lights work and all Hazard Lights work.
^ Some Hazard Lights work and all Turn Lights work.
^ Hazard Lights do not turn "OFF".

6. If Hazard Lights stay on (do not flash) in "Hazard", but Stop Lights operate normally, replace the Hazard Flasher.
7. If Stop Lights do not turn "OFF" adjust/replace the Stoplamp Switch.
8. If a Turn Indicator does not light but the Turn Signal works, check the bulb, connections and wiring to the Indicator.
9. If only one light does not operate, check the lamp, socket and related wiring for opens or corrosion.
10. With Twilight Sentinel, if Parking Lights stay on and headlights stay at full intensity with daylight conditions check for an obstruction covering the Twilight Sentinel Photocell.
11. If one Front Park and/or Marker Lamp does not light, check that its ground is clean and tight.
12. If none of the Park/Taillamps work, check Fuse 14. If open, check for short to ground in CKT 240.
13. If Park Lights do not turn "OFF", check Headlight Switch. If OK, repair short to B+ in CKT 9.
