Note


  • If a power window regulator motor assembly has been replaced with a new one, initialize the power window control system.

  • If a power window regulator motor assembly and door window regulator sub-assembly have been removed and installed, or if a power window regulator motor assembly was reused when a door glass or roof side rail weatherstrip was replaced, initialize the power window control system.

Tech Tips
