Standard Ignition LR-35 Sunroof Relay

Sunroof Relay for OE-Style Electrical Control

Standard Ignition LR-35 is a 12-volt, 30-amp sunroof relay built for reliable electrical switching in automotive body and lighting systems. It uses a square connector shape, 5 male blade terminals, and a blade-style terminal design for direct relay replacement in supported applications.

Compatible With Cadillac Eldorado, Cadillac Seville, Cadillac DeVille, Buick Riviera, Audi A6, and other listed vehicles, this relay supports sunroof and related relay functions where the original part uses the same terminal layout. The LR-35 is a practical replacement for drivers addressing intermittent relay operation or failed electrical switching.

Key Features

• 12-volt relay with a 30 amp amperage rating
• Square connector shape with 5 male blade terminals
• Blade terminal design for relay-style electrical circuits
• Composite housing helps protect the relay in harsh temperature and under-hood conditions
• Brass or copper contacts are used where specified for wear resistance
• Manufactured under TS16949 and ISO9001 certified quality systems

Detailed Description

Standard Ignition LR-35 is engineered as a replacement sunroof relay for vehicles that require a 5-blade relay configuration. It is listed for a wide range of applications, including 1982-1987 Volkswagen Quantum, 1971-1977 Volkswagen Beetle, 1984-1987 Audi 4000 and 4000 Quattro, 1986-1988 Audi 5000 Quattro, 1995 Audi A6 and A6 Quattro, and multiple Cadillac, Buick, Oldsmobile, and Pontiac models. In several Cadillac Eldorado, Seville, DeVille, Fleetwood, and Commercial Chassis applications, it is also referenced for automatic transmission spark control relay use.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. Standard Ignition LR-35 is built with controlled manufacturing processes and OE-focused quality standards to help maintain consistent relay performance across supported vehicle platforms.

What It Helps Solve

• Sunroof relay failure causing inoperative roof movement
• Intermittent electrical switching in relay-controlled circuits
• Worn relay contacts leading to inconsistent operation
• Heat-related relay degradation in demanding vehicle environments
• Replacement needs for 5-blade terminal relay applications

Installation Notes and Tips

Verify the connector shape, terminal count, terminal gender, and voltage before installation. This relay uses a square connector with 5 male blade terminals and is not a continuous-duty relay. Confirm the vehicle’s original relay configuration and application notes, especially on Cadillac models where the part may also be listed for automatic transmission spark control relay use.

Quality Assurance

Standard Ignition manufactures this relay under TS16949 and ISO9001 certified processes with quality control from component selection through final assembly. Composite housing construction and specified metal contacts support consistent electrical performance in the listed applications.
