Description

Manage your A/C and heater fan speeds with the Standard Ignition Blower Motor Resistor, part number RU-109. It is designed to restore variable speed control of the blower motor, supporting HVAC performance and passenger comfort. It fits many vehicles, among them the 1994-2002 Dodge Ram 1500, 1994-2002 Dodge Ram 2500 and 1993-1999 Jeep Grand Cherokee. See the Buyer's Guide tab for the full list and engine details.

The resistor limits the current that reaches the blower motor so the fan can run at its lower speed settings. Key construction details:

Copper electrical connectors: Premium copper connectors help deliver more precise resistance values. This improves resistor performance and offers a longer part life.
Kanthal D resistor wire: Adds flexibility, durability and tensile strength to the wiring attached to the higher-watt resistors.
HVAC integration: The research and design process is aimed at a seamless fit with the vehicle's HVAC system.
Tested in-house: The part undergoes extensive testing at the manufacturer's facility to confirm correct performance in all conditions.

A failed resistor can leave the blower running only on its highest setting or skipping some fan speeds. If the resistor is the cause, installing RU-109 replaces the faulty unit. Diagnose the problem before you replace anything, because a worn blower motor, a faulty switch or damaged wiring can cause similar symptoms.

Frequently Asked Questions

What does an HVAC blower motor resistor do?

It controls the current reaching the blower motor so the fan can run at different speed settings. The RU-109 is designed to restore variable speed control for both the A/C and the heater.

Will this Jeep Grand Cherokee blower motor resistor fit my 1993-1999 model?

Yes. The RU-109 is listed for the 1993-1999 Jeep Grand Cherokee. The Buyer's Guide tab shows the complete application list.

Is this a blower motor resistor for the 1994-2002 Dodge Ram 1500?

Yes. It is listed for the 1994-2002 Dodge Ram 1500 and the 1994-2002 Dodge Ram 2500. The Buyer's Guide tab shows every application.

What are signs a blower motor resistor may need replacing?

Common signs are a blower that works only on its highest setting or skips some fan speeds. A blower motor, switch or wiring fault can cause similar symptoms, so diagnose the problem before replacing parts.

What is the RU-109 built with?

It uses premium copper electrical connectors for more precise resistance values. It also uses Kanthal D resistor wire for flexibility, durability and tensile strength in the wiring on the higher-watt resistors.
