• The window regulator is the mechanical mechanism inside the car door that raises and lowers the glass when you press the window switch. Without a functioning regulator, the glass may not move, may bind, or may drop.
• A “without motor” version means you get the regulator/mechanism portion – the gears, tracks/cables, guides – but you reuse or replace the motor separately.
• Having a correct regulator ensures the window travels smoothly, stays aligned, seals properly, and doesn’t sag or fall into the door.

• The window does not move up or down when you press the switch, yet you may hear the motor trying.
  
• The window moves slowly, jerks, gets stuck, or stops midway — indicating the regulator mechanism is worn, binding or damaged.
  
• Grinding, clicking or scraping noises when operating the window — the cable, track or gears inside the regulator may have failed.
  
• The glass appears crooked, tilts, drops inside the door or fails to stay up — regulator failure can cause misalignment.
