Test 26A - Both Headlamps Out

1994 Plymouth Sundance Base, 2D Hatchback, 2.2 D, AutomaticSECTION Test 26A - Both Headlamps Out
WARNING: This page is about a different car, the 1994 Chrysler LeBaron. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATIONΒ  . For wiring diagram, see WIRING DIAGRAMSΒ  . Perform TEST VER-1 after each repair.
  1. Turn ignition switch to OFF position. Disconnect low beam headlamp relay. See Figure . Check, clean and repair connections as needed. Turn ignition switch to ON position. Put DRB in voltmeter mode. Measure voltage at headlamp relay connector terminal "A" (Red/White wire). If voltage is more than 10 volts, go to step 4). If voltage is less than 10 volts, go to next step.
  2. Measure voltage at headlamp relay connector terminal "B" (Red/White wire). If voltage is more than 10 volts, repair open Red/White wire between headlamp relay terminal "B" and power distribution center. If voltage is less than 10 volts, go to next step.
  3. Inspect headlamp system 40-amp fuse (second fuse from right on bottom row) at power distribution center, located in front of left strut tower. See Figure . If fuse is okay, go to TEST 26B. If fuse is open, go to TEST 26CΒ  .
  4. If voltage is more than 10 volts in step 1), measure voltage at headlamp relay connector terminal "B" (Red/White wire). If voltage is less than 10 volts, repair open Red/White wire between headlamp relay connector terminal "A" and power distribution center. If voltage is more than 10 volts, go to next step.
  5. Put DRB in ohmmeter mode. Ensure headlamp switch is in ON position. Measure resistance at headlamp relay connector terminal "C" (Orange/White wire). If resistance is less than 5 ohms, go to step 8). If resistance is more than 5 ohms, go to next step.
  6. Disconnect left pod switch connector. See Fig 1 . Check, clean and repair connections as needed. Measure resistance at left pod switch connector terminal No. 13 (Black/Orange wire). If resistance is more than 5 ohms, repair Black/Orange wire between left pod switch connector and ground for open to ground. If resistance is less than 5 ohms, go to next step.
  7. Using an external ohmmeter, measure resistance between left pod switch connector terminal No. 12 (Orange/White wire) and headlamp relay connector terminal "C" (Orange/White wire). If resistance is more than 5 ohms, repair open Orange/White wire between left pod switch connector and headlamp relay connector. If resistance is less than 5 ohms, replace headlamp switch, located in left pod switch.
  8. If resistance is less than 5 ohms in step 5), use an external ohmmeter to measure resistance between headlamp relay connector terminal "D" (Violet/White wire) and fuse No. 17 (Violet/White wire). See Figure . If resistance is less than 5 ohms, replace low beam headlamp relay. See Figure . If resistance is more than 5 ohms, repair open Violet/White wire between headlamp relay connector and fuse panel.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • β€’ You smell fuel, burning insulation, or see smoke.
  • β€’ Brakes feel soft, pull hard to one side, or make grinding noises.
  • β€’ The engine overheats, stalls repeatedly, or misfires under load.
  • β€’ You are missing required tools, torque specs, or safe lifting equipment.
  • β€’ You are not confident in the next step or safety outcome.
