It uses a rectangular female connector, 4 male blade terminals, and an included mounting bracket for a direct-fit style replacement in select Chrysler, Dodge, and Plymouth applications.

Key Features

• 12-volt HVAC temperature delay relay for A/C clutch control applications
• 25 amp amperage rating for controlled electrical switching
• Rectangular female connector with 4 male blade terminals
• Mounting bracket(s) included for secure installation

Detailed Description

Standard Ignition RY-189 is an HVAC temperature delay relay designed for vehicles that use relay-based A/C clutch control. It is a practical replacement for select 1988-1992 Dodge Dakota models, along with 1989 Chrysler Daytona, 1989 Chrysler LeBaron, 1989 Dodge Aries, 1989 Dodge Daytona, 1989 Dodge Lancer, and 1989 Plymouth Reliant applications. This part number also appears in cross-reference listings for Davico Mfg 19244 and FEL-PRO 35996.

Built with a composite housing and quality-controlled manufacturing, RY-189 is made to handle demanding underhood temperatures while maintaining consistent relay function. If you are servicing an HVAC temperature delay relay on a Dodge Dakota or a Chrysler Daytona, this relay provides the electrical switching needed for proper A/C clutch operation.

What It Helps Fix

• A/C clutch not engaging when the HVAC system calls for cooling
• Intermittent compressor clutch operation caused by relay failure
• Delayed or inconsistent HVAC electrical switching
• Heat-related relay breakdown in the engine compartment
• Fault codes or drivability complaints tied to relay-controlled A/C clutch circuits

Installation Notes and Tips

Verify connector style, terminal layout, and mounting location before installation. Standard Ignition RY-189 uses a female rectangular connector with 4 male blade terminals, so matching the original relay configuration is important for proper fitment. Confirm the vehicle’s HVAC relay location and inspect the connector for heat damage, corrosion, or loose terminals before installing the replacement.
