Detailed Product Description

The RU-104 blower motor resistor from Standard Ignition is engineered to provide consistent blower motor speed regulation in HVAC systems. It features a screw attachment method for a firm and stable fit within the HVAC housing. The resistor includes a single female rectangular connector cavity, designed to interface with the vehicle’s wiring harness (harness not included). With seven male blade terminals, it ensures proper electrical contact and durability under typical operating conditions.

This resistor is compatible with multiple Chrysler, Dodge, and Plymouth models, including the Chrysler 300M, Dodge Breeze, Cirrus, Concorde, Intrepid, LHS, Sebring, and Stratus. It supports blower motors with 3 to 5 speed settings, making it suitable for a range of HVAC blower motor configurations found in these vehicles.

Common Applications and Issues Resolved

• Restores proper blower motor speed control in Chrysler 300M and Dodge Intrepid HVAC systems
• Eliminates blower motor stuck on one speed or no speed issues
• Fixes intermittent blower motor operation in Plymouth Sebring and Dodge Stratus
• Addresses overheating or resistor failure symptoms causing HVAC malfunction
• Improves overall climate control performance in compatible vehicles

Installation Notes and Tips

• Ensure the vehicle’s ignition is off before installation
• Remove the old resistor by unscrewing the mounting screws carefully
• Verify the connector shape and terminal configuration match the RU-104 resistor
• Do not attempt to splice wiring; this resistor requires a direct plug-in connection
• Check for any debris or corrosion in the connector area before installing the new resistor
