Detailed Product Overview

Standard Ignition DS-574 is a replacement wiper switch for a wide range of Ford and Mercury vehicles from 1973-1991. It is engineered for service work where reliable switch operation matters, especially on older vehicles with intermittent wiper functions. This part cross-references Standard Ignition (e.g., SW1117, WS6161) for the same application.

Use DS-574 when servicing intermittent wiper control on classic Ford E-Series vans and club wagons, along with passenger cars such as the Ford Mustang, Pinto, and Thunderbird. The part number DS-574 is also commonly searched for Ford E-150 Econoline and Mercury Cougar intermittent wiper repairs.

Common Problems This Part Can Address

• Intermittent wipers that do not cycle correctly
• Wiper switch failure at the dash control
• Inconsistent electrical contact in the switch circuit
• Loss of intermittent wipe function on older Ford and Mercury vehicles
• Switch operation issues caused by worn internal contacts

Installation Notes and Tips

Verify connector style, terminal count, and vehicle application before installation. DS-574 uses a female connector, male blade terminals, and an 8-terminal layout, so matching the original switch configuration is important for proper fit and function. Confirm the vehicle is equipped with intermittent wipers before ordering.
