Dorman’s kit supplies a direct-fit resistor and the matching harness pigtail so you can swap a corroded or overheated factory resistor without splicing or jury-rigging. The part is engineered to match original equipment form and function and is supported by product engineering and quality checks in the U.S.\u003c\/p\u003e\n\n\u003ch3\u003eHow will this kit fix blower fan speed issues?\u003c\/h3\u003e\n\u003cp\u003eWhen a blower motor resistor fails, certain fan speeds (often low or medium) stop working because the resistor stages that reduce current are bypassed or open. Replacing the resistor and its connector restores the circuit paths that provide multiple speed settings.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eIncludes resistor element and harness pigtail for a complete repair\u003c\/li\u003e\n  \u003cli\u003eRecreates original electrical pathways to restore all fan speed options\u003c\/li\u003e\n  \u003cli\u003eEliminates the need to bypass or splice the factory wiring\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eIs this Dorman part a direct replacement for the factory resistor?\u003c\/h3\u003e\n\u003cp\u003eYes — this kit is manufactured to directly replace the original equipment resistor on specified model years and trims.
