A-Premium Manual HVAC Blower Motor Resistor for Dodge/Ram 4-Pin Connector — OE Fit, 3–5 Speed

A-Premium's 4-pin manual HVAC blower motor resistor is a direct-fit replacement for select Dodge and Ram trucks without automatic temperature control, restoring multi-speed fan operation quickly and reliably.

If your truck's heater or AC fan is stuck on one speed or doesn't respond at certain settings, the blower motor resistor is a common wear item to check. This A-Premium resistor is built to OE dimensions and terminal layout so it installs in place of the original unit on compatible Ram and Dodge models. It supports 3–5 speed blower configurations and includes the female connector and four male pin terminals required for these vehicles.

Which Dodge and Ram models will this resistor fit?

This resistor is compatible with many Dodge Ram pickup years that use a manual HVAC system (no automatic temperature control). Fitment covers Ram 1500, 2500, 3500 and larger models across several model years—always verify your truck's year and original part number.

• Ram 1500: 2009–2010 and 2011–2014, plus some 2018 models
• Ram 2500/3500: 2010 and 2011–2018
• Also applicable to Ram 4500/5500 models listed for 2011–2018 without ATC
• Cross-reference numbers: RU-710, 973-189, 68048900AA, 68048900AB

How do I install the A-Premium blower resistor?

Installation is straightforward for anyone comfortable with basic hand tools; the part is made to OE specifications so it replaces the old resistor without modification. Remove the fasteners, unplug the wiring harness, swap the old resistor for the new unit, and resecure the screws.

• No wiring harness included—use the vehicle’s original connector
• Female connector with one housing and four male pin terminals ready to mate
• Fits into the factory mounting location using existing screw points
• Works with 3–5 speed blower motor systems

What electrical and physical specs should I check before buying?

Confirm the connector and terminal style match your original part and that your truck uses manual temperature controls. Check the part reference numbers on your existing resistor to ensure exact compatibility.

• Connector gender: female; terminal gender: male
• Terminal type: pin; terminal quantity: 4
• Number of speeds supported: 3 to 5 speed systems
• Compare original part numbers (RU-710, 973-189, 68048900AA/AB)
