Test D: One Low Beam Headlight Inoperative
WARNING: This page is about a different car, the 2002 Lincoln Blackwood and 2002 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
Disconnect inoperative headlight harness connector. Turn headlights on. Place multifunction switch in low beam position. Measure voltage between ground and inoperative headlight harness connector (Dark Green/Orange wire for right side; Dark Blue/White wire for Left side). If battery voltage exists, replace headlight bulb. See HEADLIGHT BULB under REMOVAL & INSTALLATION. If battery voltage does not exist, repair open in appropriate wire. See WIRING DIAGRAMS .
