3. If Headlight Doors open slowly, check for clean and tight ground G115 and fully charged Battery.
4. If Headlight Doors open only partially, perform Chart #1 - Both Headlight Doors Remain Open or Closed.

^ Check for a broken (or partially broken) wire inside of the insulation which could cause system failure but prove "GOOD" in a continuity/voltage check.
