Wells 1R1238 Multi-Purpose Automotive Relay

The Wells 1R1238 is an automotive relay designed and manufactured to meet or exceed original equipment manufacturers' specifications for performance and durability. This multi-purpose relay is used to control electrical circuits for components on a vehicle that have a high amperage load such as headlights, fuel pumps and cooling fans.

Key Features:

• Matches OE part in fit, form and function
• Custom application specific integrated circuit provides accurate resettable thermal shutdown and overvoltage protection to guard against abnormal conditions
• Relays that operate motors typically have diodes which provide circuit protection
• Precise OEM connector design for direct replacement installation

A malfunctioning or inoperative multi-purpose relay will cause a component to not function or function intermittently. Depending on which circuit is affected, a failed multi-purpose relay could cause a no-start condition, proper vehicle operation and impaired safety systems. This replacement relay restores proper electrical circuit operation and ensures reliable vehicle performance.
