Product Details

The Standard Ignition DS-1664 is a replacement door jamb switch for Lexus LS430 models from 2001 through 2006. It uses a normal activation style and a direct-mount design, making it a practical choice when restoring door-triggered interior lighting, warning chimes, or related body electrical functions. This part cross-references 8423150120 and SW3670 for the same application. Standard Ignition DS-1664 is a focused replacement for the front left and front right door jamb switch locations on the Lexus LS430.

Common Issues This Part Can Address

  • Interior lights that stay off when the door opens
  • Courtesy lights that remain on after the door closes
  • Door-open warning chime not triggering correctly
  • Intermittent switch contact at the door jamb
  • Worn or damaged original switch housing

Installation Notes and Tips

Verify connector shape, terminal style, and plunger length before installation. Inspect the door jamb area for corrosion, bent terminals, or damaged wiring before connecting the new switch. Confirm proper switch alignment after mounting so the plunger contacts the door cleanly and the electrical circuit changes state as the door opens and closes.

Quality Assurance

Standard Ignition supplies replacement electrical components for service applications, and DS-1664 is built to match the listed connector, terminal, and mounting configuration for the specified Lexus LS430 fitment.
