Standard Ignition RL-2 HVAC Temperature Delay Relay

HVAC Temperature Delay Relay for Ford Applications

Standard Ignition RL-2 is a 12-volt HVAC temperature delay relay built for Ford and Lincoln vehicles that use a 3-blade terminal layout in select applications. It features a rectangular connector shape, male blade terminals, and a mounting bracket for secure installation in the HVAC circuit.

Key Features

• 12-volt HVAC temperature delay relay
• 25 amp amperage rating
• Rectangular connector with 3 male blade terminals
• Mounting bracket(s) included
• Composite housing for resistance to heat and underhood conditions
• Brass or copper contacts where specified for wear resistance
• Manufactured under TS16949 and ISO9001 quality systems

Detailed Description

The Standard Ignition RL-2 is an HVAC temperature delay relay used in climate control circuits where timed relay operation is required. Standard Ignition RL-2 is built with durable composite housing materials and controlled-contact construction to support consistent electrical performance in demanding automotive environments. This relay cross-references Carlson 16137 for the same application.

Compatible With Ford F-150, Ford F-250, Ford F-350, Ford Ranger, Ford Bronco, Ford Aerostar, Ford E-Series vans, and select Lincoln and Mercury models across 1972-1993 applications. It is also listed for vehicles such as the Ford LTD, Lincoln Continental, and Mercury Grand Marquis in specific configurations, including 3-blade terminal versions where noted.

Common Problems This Relay Can Help Address

• HVAC relay failure that interrupts temperature control operation
• Delayed or inconsistent blower or climate circuit response
• Electrical wear at relay contacts from repeated cycling
• Heat-related relay housing damage in underhood locations
• Fitment issues when replacing a 3-blade terminal HVAC relay

Installation Notes and Tips

• Verify the connector shape, terminal count, and blade style before installation.
• Confirm the vehicle’s original relay specification matches the 12-volt, 25-amp rating.
• Use the mounting bracket to secure the relay in the original location.
• Check the HVAC circuit and related wiring for corrosion or heat damage before replacing the relay.
• Review the vehicle-specific notes for 3-blade terminal applications on select Ford, Lincoln, and Mercury models.

Quality Assurance

Standard Ignition manufactures this relay under stringent quality requirements with complete process control from component selection through finished product. TS16949 and ISO9001 certified plants support consistent production standards for the RL-2.
