Standard Ignition RU994 HVAC Blower Motor Resistor
Standard Ignition RU994 is an electronic HVAC blower motor resistor built for vehicles that use a 3- to 5-speed blower control with a 3-position switch. It features a bolt-on metal housing, a single male connector, and 4 blade terminals for a direct electrical connection in the HVAC case.
Use RU994 when servicing blower speed control on applications such as Dodge Ram and Jeep Cherokee HVAC systems where the resistor pack is part of the cabin air handling circuit. The RU994 part number is also referenced for cross-application matching in aftermarket catalogs.
Key Features
- Electronic coil type for blower speed control
- Bolt-on attachment method for secure mounting
- Metal housing with black and silver finish
- 1 male connector and 4 male blade terminals
- Supports 3- to 5-speed blower motor systems
- 3 switch positions
- Standard Ignition RU994 replacement part number
Detailed Description
This HVAC blower motor resistor regulates blower fan speed by controlling current flow to the cabin blower motor. Standard Ignition RU994 is built with an electronic coil design and a metal housing to match common OE-style HVAC resistor layouts. It is a practical replacement for vehicles that use a bolt-on resistor assembly with a single connector and blade-style terminals.
For buyers searching for a Dodge Ram blower motor resistor, Jeep Cherokee blower motor resistor, or RU994 HVAC resistor replacement, this part provides the electrical interface and mounting style commonly used in blower speed control repairs. This part cross-references Four Seasons 20901 for the same application.
What It Is Used For
- No blower fan speeds or only certain speeds working
- Intermittent cabin airflow from the HVAC vents
- Blower motor stuck on one speed setting
- Heat or A/C fan control not responding correctly
- Electrical resistance failure in the blower control circuit
Installation Notes and Tips
Install RU994 at the HVAC case using the bolt-on mounting points and verify the connector and terminal layout before installation. Inspect the blower motor connector, wiring, and related HVAC control components for heat damage or corrosion, since resistor failure is often linked to excess current draw or damaged terminals. Confirm the vehicle uses a 3- to 5-speed blower system with a 3-position switch before ordering.
Quality Assurance
Standard Ignition is a recognized aftermarket brand for electrical and HVAC service parts. RU994 is built to match the specified connector, terminal, and mounting configuration for the listed application type.
