When the cab fan won't step through its speeds, the Dorman blower motor resistor and harness kit, part number 984-693, is designed to replace an overheated or corroded original equipment resistor. It is a direct-fit replacement for the 2005-2020 Toyota Tacoma. See the "Vehicles it fits" section for engine details.
The blower motor resistor helps control how fast the HVAC blower motor spins, so the fan runs at the speed selected for heating, cooling and defrost. Dorman pairs a new resistor with a fresh harness pigtail so the connection is addressed along with the resistor itself.
- Direct replacement: directly replaces the original equipment resistor on the listed applications.
- Resistor plus pigtail: each kit includes a resistor and a harness pigtail, which Dorman notes is essential for most repairs.
- OE-like performance: made to perform like original equipment, helping the HVAC system operate as designed.
- Engineering backing: supported by Dorman's team of engineers and quality specialists in the USA.
Signs this part may need replacing include a blower that runs only on its highest setting, lower speeds that no longer work, a fan that won't run at all, or a connector that looks overheated or corroded. A faulty switch, motor or wiring can cause similar symptoms, so diagnose the cause first. If the resistor or its connector has failed, this Dorman HVAC blower motor resistor kit supplies both.
