Trouble Shooting: Notes

NOTE: To prevent misdiagnosis, ensure that no Diagnostic Trouble Codes (DTCs) exist. See BODY CONTROL MODULE article.

Perform before beginning system diagnosis:

  • Check PWR WDO (30-amp) circuit breaker.
  • Ensure grounds are clean and tight.
  • If only master window switch operates windows, ensure LOCKOUT is not engaged (4 door).
  • Check for broken or partially broken wire inside insulation which would cause system failure but prove good in continuity/voltage check.
  • Ensure proper installation of aftermarket electronic equipment that may affect integrity of other systems.
