Detailed Product Overview

Standard Ignition DS-2354 is a replacement door window switch engineered to restore normal power window operation in the 1999, 2000, 2001, and 2002 Mercury Cougar, left position. It is manufactured to OE spec so the switch matches the original electrical and physical requirements of the vehicle. The copper alloy conductor design supports efficient current flow, while the durable housing and internal materials are built for consistent service performance. This part number, DS-2354, is a practical choice when the original driver window switch has worn contacts, intermittent response, or complete failure.

This part cross-references Ford OE-style numbers such as F8RZ14529KB and aftermarket references such as SW6636 for the same application.

Common Problems This Switch Can Address

  • Driver window does not respond when the switch is pressed
  • Intermittent power window operation
  • Sticking, worn, or unresponsive switch contacts
  • Loss of driver-side window control in a Mercury Cougar
  • Electrical issues traced to the door window switch assembly

Installation Notes and Tips

Verify connector style, terminal count, and switch position before installation. This DS-2354 uses a female connector, 4 blade terminals, and a 12-volt electrical layout. Confirm the vehicle is a 1999-2002 Mercury Cougar, left side for the driver’s window, and inspect the harness and terminals for corrosion or damage before connecting the new switch.

Quality Assurance

Standard Ignition manufactures switches to OE specifications and maintains quality control throughout the production process to support proper fit, form, and function.
