Detailed Description

Standard Ignition US-175 is engineered for service replacement where reliable key-to-electrical switching is required at the steering column. The switch construction uses high-grade materials to support consistent fit and function, while the copper alloy conductor design helps maintain stable conductivity across the ignition circuit. This part cross-references 1S6209 and KS6517 for the same application. Fits 1988 Buick Reatta, N/A; Fits 1986-1988 Buick Riviera, N/A; Fits 1987-1988 Cadillac Allante, N/A; Fits 1987-1988 Cadillac Eldorado, N/A; Fits 1987-1988 Cadillac Seville, N/A; Fits 1986 Cadillac Eldorado, N/A w/o Tilt Wheel; w/ Electronic Cluster.

Common Issues This Part Can Address

• Intermittent no-start condition caused by worn ignition switch contacts
• Electrical accessory or ignition circuit loss at the column
• Key position issues that prevent proper start, run, or accessory operation
• Switch failure related to heat, wear, or internal contact degradation
• Inconsistent electrical switching performance in the ignition circuit

Installation Notes and Tips

Verify the connector style, terminal count, and column mounting location before installation. This application uses a bolt-on design with a single rectangular connector and 10 blade terminals, so matching the original switch configuration is important. For 1986 Cadillac Eldorado, confirm the vehicle is equipped without tilt wheel and with electronic cluster before ordering. Standard Ignition US-175 is a direct-fit style replacement for select Buick Riviera, Buick Reatta, Cadillac Allante, Cadillac Eldorado, and Cadillac Seville applications.

Quality Assurance

Standard Ignition states that this switch is built with robust materials, copper alloy conductors, and full mechanical and electrical testing to verify switching performance before release.
