Wells 1S15840 Power Door Lock Switch

The Wells 1S15840 is a direct-replacement power door lock switch engineered by Wells Vehicle Electronics, a leading global manufacturer of professional-grade vehicle electronics for OE and aftermarket applications. This switch serves as the primary driver-operated control for the vehicle's power door lock system, sending the electrical signal to the door lock actuators to lock or unlock the doors.

Key Features:

• Controls current flow to the door lock actuators for proper lock and unlock operation
• Designed to meet or exceed OE specifications in form, fit, and function
• Direct plug-in replacement — no wiring modifications required
• Built with quality materials for long-term reliability and durability
• Manufactured by Wells Vehicle Electronics, a trusted global supplier of advanced vehicle electronics solutions

A failing door lock switch can cause the power locks to stop responding, operate intermittently, or remain engaged continuously — symptoms that can also accelerate premature wear on the door lock actuators. Replacing the switch with a precision-engineered Wells unit restores reliable operation and helps protect the rest of the door lock system.
