High Beam Headlights Will Not Turn On
NOTE:
After making any repairs, perform BODY VERIFICATION TEST
under VERIFICATION TESTS.
- Turn ignition off. Remove circuit breaker No. 2 (25-amp) from fuse block. Check voltage at circuit breaker input terminal No. 43 in fuse block. If battery voltage exists, go to next step. If battery voltage does not exist, repair power supply circuit. See POWER DISTRIBUTION in SYSTEM WIRING DIAGRAMS article in ELECTRICAL.
- Check circuit breaker No. 2 from fuse block. If circuit breaker is blown, go to next step. If circuit breaker is okay, go to step 5 .
- Disconnect Gray 20-pin multifunction switch connector located on steering column. Check resistance between multifunction switch harness connector terminal No. 16, low beam output circuit and ground. See Fig 1 . If resistance is more than 5 ohms, go to next step. If resistance is 5 ohms or less, repair short to ground on wire.
- Check resistance between multifunction switch harness connector terminal No. 17, high beam output circuit and ground. If resistance is more than 5 ohms, replace circuit breaker and recheck system. If resistance is 5 ohms or less, repair short to ground on wire.
- Install circuit breaker. Disconnect Gray 20-pin multifunction switch connector located on steering column. Check voltage at multifunction switch connector terminal No. 19. If battery voltage exists, go to next step. If battery voltage does not exist, repair open on wire between fuse block and multifunction switch.
- Using jumper wire, connect multifunction switch harness connector terminals No. 17 and No. 19. If headlights illuminate, replace multifunction switch. If headlights do not illuminate, repair wire between multifunction switch and headlights.
