Featuring an electronic coil design, this resistor manages the electrical current to the blower motor, enabling multiple speed settings ranging from three to five speeds. The bolt-on attachment method and included mounting brackets facilitate a straightforward installation process. The resistor is equipped with a female connector featuring two connectors shaped in square and rectangle forms, designed to interface with six blade-type male terminals. This configuration ensures a secure and reliable electrical connection without the need for additional wiring harnesses or hardware.\u003c\/p\u003e\u003ch2\u003eCompatible Vehicles and Applications\u003c\/h2\u003e\u003cp\u003eThis HVAC blower motor resistor is compatible with the following vehicles:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eChrysler 300M\u003c\/li\u003e\n\u003cli\u003eChrysler Concorde\u003c\/li\u003e\n\u003cli\u003eChrysler Intrepid\u003c\/li\u003e\n\u003cli\u003eChrysler LHS\u003c\/li\u003e\n\u003cli\u003eChrysler New Yorker\u003c\/li\u003e\n\u003cli\u003eDodge models matching the above platforms\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon Issues Addressed by RU-383 Resistor\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBlower motor stuck on a single speed\u003c\/li\u003e\n\u003cli\u003eHVAC blower not responding to speed control settings\u003c\/li\u003e\n\u003cli\u003eIntermittent blower motor operation\u003c\/li\u003e\n\u003cli\u003eOverheating or failure of blower motor resistor\u003c\/li\u003e\n\u003cli\u003eLoss of multiple blower speeds in HVAC system\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eInstallation of the Standard Ignition RU-383 blower motor resistor requires removal of the old resistor and securing the new unit using the bolt-on method. The included mounting brackets ensure proper alignment and fitment. Since no wiring harness or hardware is included, reuse existing connectors and hardware from the original resistor. Verify connector orientation—female connectors with square and rectangular shapes—and ensure all six blade terminals are properly seated. It is recommended to disconnect the vehicle battery before installation to prevent electrical shorts.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eStandard Ignition parts are manufactured to meet or exceed OEM specifications for fit, form, and function.
