Turn Signal Switch for Chevrolet and GMC Vans

Standard Ignition TW-22 is a new turn signal switch built for older Chevrolet and GMC van and truck applications that require dependable electrical switching. It uses copper alloy conductors for strong conductivity and low resistive loss, with 100% testing for mechanical and electrical performance.

Key Features

• Turn signal switch for steering column applications
• Male connector and male blade terminals
• 2 connector cavities and 8 terminals
• New replacement part from Standard Ignition
• Built with copper alloy conductors for stable electrical flow
• 100% tested for switching performance before release

Detailed Description

The Standard Ignition TW-22 is a direct replacement turn signal switch for select 1973-1979 Chevrolet and GMC vehicles, including Chevrolet G10, G20, G30, P10, P20, and P30 models, plus GMC G15, G25, G35, G1500, G2500, G3500, and G15/G1500 Van, G25/G2500 Van, and G35/G3500 Van applications. It is listed for vehicles with and without tilt wheel configurations as noted in the fitment data, and it includes hazard switch-related applications where specified. This part number, TW-22, is engineered for service work where accurate signal operation and reliable electrical contact are required.

This part cross-references Standard Ignition S3235 for the same application.

What It Helps Fix

• Turn signals that do not activate or cancel correctly
• Intermittent signal operation caused by worn internal contacts
• Hazard switch function issues tied to the column switch assembly
• Electrical resistance problems from degraded switch conductors
• Column switch failures in older Chevrolet and GMC van platforms

Installation Notes and Tips

Verify steering column configuration before ordering, especially tilt wheel versus non-tilt wheel applications. Match the connector style, terminal count, and hazard switch notes to the original part. Confirm vehicle fitment for your exact Chevrolet G10, G20, G30, P10, P20, P30, or GMC G15/G1500 Van, G25/G2500 Van, and G35/G3500 Van application before installation.

Quality Assurance

Standard Ignition builds this switch with robust materials and copper alloy conductors, then tests each unit for mechanical and electrical switching performance. The TW-22 reflects the brand’s long-term focus on technician-oriented electrical replacement parts.
