FAERSI HVAC Blower Motor Resistor Kit for 2005-2018 Toyota Tacoma — Direct-Fit with Wire Harness

FAERSI's 973-582 HVAC fan blower motor resistor kit with wire harness restores stepped fan speeds for Toyota Tacoma models from 2005 to 2018.

If your Tacoma's heater or A/C blows at only one speed or the blower behaves inconsistently, a failed blower motor resistor is often the cause. This kit from FAERSI replaces factory part numbers including 87138-04052, RU746, RU1435, JA1772 and 4P1650, and arrives with a matching wiring harness so you get a direct-fit replacement without splicing or modifications.

How does this resistor kit fix inconsistent fan speeds?

The blower motor resistor controls fan speed by varying electrical resistance in the blower circuit. Replacing a worn or burnt resistor with this FAERSI module restores the correct resistance values and enables all fan speed positions to function again. Installation uses the included harness so the electrical connections match the original factory layout.

• Direct replacement for listed OEM numbers (973-582, 87138-04052, etc.).
• Includes wire harness for plug-and-play connection.
• Restores low, medium and high HVAC blower settings.

Will this fit my specific Toyota Tacoma year and trim?

This blower motor resistor kit is designed for manual (non-automatic) HVAC controls on Toyota Tacoma model years 2005 through 2018. Before buying, confirm compatibility by checking your vehicle year and the OEM/interchange numbers printed on the original resistor. If your truck uses different HVAC systems (automatic climate control), this part may not be compatible.

• Fits 2005–2018 Toyota Tacoma with manual fan controls.
• Cross-references: 8713804052, 8713804050, 8713804051, RU746, RU1435.
• Verify against your old part number for exact match.

How difficult is the installation and where is the resistor located?

Installation is straightforward for anyone comfortable with basic vehicle interior work and a screwdriver. The resistor assembly is typically mounted on the lower passenger side of the HVAC housing and is accessible after removing a few screws and the blower access panel. The included harness eliminates cutting or splicing, keeping installation tidy and reversible.

• Located on lower passenger side of the HVAC blower housing.
• Requires removal of a few screws—no specialized tools required.
• Includes matching harness for direct plug-in connection.

What quality and warranty support does FAERSI provide?

The FAERSI module is tested before shipping and built to meet or exceed OEM performance standards. Materials and assembly are selected for reliability and heat tolerance common to blower resistor applications. If you receive a defective or non-working unit, FAERSI offers replacement or refund options through their customer support.

• 100% tested prior to shipment.
• Constructed with components rated for HVAC blower conditions.
• Warranty/return support for defective units—contact seller for assistance.

Who is this for: This FAERSI 973-582 blower motor resistor kit is intended for DIY mechanics and professional technicians repairing 2005–2018 Toyota Tacomas that have manual fan controls and are experiencing limited or no blower speed functionality. Choose this kit if you want a direct-fit, harness-included replacement that matches common OEM part numbers and restores reliable cabin airflow control.
