Test Q: High Beam Indicator Inoperative/Always On
- Turn ignition switch to RUN position. Operate headlights in high beam position. If high beams operate, go to next step. If high beams do not operate, repair high beams as necessary. See EXTERIOR LIGHTS article.
- Turn ignition switch to LOCK position. Disconnect 20-pin instrument cluster harness connector C251. It may be necessary to remove instrument cluster for access to connector. See REMOVAL & INSTALLATION . Turn ignition switch to RUN position. Measure voltage between ground and instrument cluster harness connector C251 terminal No. 2 (Light Green/Black wire) while turning high beams on and off. See Figure . Battery voltage should exist when high beams are on and zero volts should exist when high beams are off. If voltage is as specified, go to next step. If voltage is not as specified, repair open or short to voltage/ground in Light Green/Black wire. See EXTERIOR LIGHTS article.
- Disconnect all instrument cluster harness connectors. Inspect all instrument cluster harness connectors for loose, damaged or corroded terminals. If terminals are damaged, repair as necessary. If terminals are not damaged, reconnect all instrument cluster harness connectors. Ensure instrument cluster harness connectors are seated properly. If problem still exists, replace instrument cluster module.
