Motoforti Blower Motor Resistor for Grand Cherokee 2011-2013, Black Metal Direct Replacement, Automatic Temp Control

Motoforti Blower Motor Resistor is a metal-plastic direct replacement part that restores HVAC fan speed control on compatible Chrysler, Dodge and Jeep models.

This replacement blower motor resistor fits select Chrysler, Dodge and Jeep vehicles and is designed for systems with automatic temperature control. Built from durable metal and plastic, this unit replaces worn or failed resistors to reestablish stepped fan speeds and reliable ventilation. It comes pre-configured for an easy swap, matching common original equipment numbers so you can return the HVAC blower to normal operation without modifications.

Which vehicles will this Motoforti blower resistor fit?

This part is manufactured to match the fitment and mounting points found on several model years of Chrysler, Dodge and Jeep vehicles. It works with specific engines and model years where the original resistor part numbers are listed.

• Chrysler 300: 2.7L, 3.5L, 3.6L (2008–2013, 2018)
• Chrysler Pacifica: 3.6L (2017–2022)
• Chrysler Town & Country: 3.3L (2008–2010), 3.6L (2011–2016)
• Dodge Charger, Durango, Grand Caravan, Magnum and Jeep Grand Cherokee: select years and engines (see OE numbers for exact matches)

How does this resistor restore blower fan performance?

The resistor provides different electrical resistance levels to the blower motor so the HVAC fan can operate at multiple speeds. When the original resistor fails, the fan often gets stuck at one speed or stops working entirely; replacing it restores the intended speed steps and reliable air circulation.

• Re-establishes multiple fan speeds for the HVAC system
• Prevents the blower from running at one speed or not at all
• Directly swaps into the original connector and mounting location

Is installation difficult and what tools are required?

Installation is straightforward for most DIYers and professional technicians because this unit is built as a direct replacement. No special tools are required beyond common hand tools, and the plug-and-play design minimizes wiring or cutting.

• Direct replacement—no cutting or splicing
• Requires common tools like a screwdriver or small socket set
• Typical installation time: 15–45 minutes depending on vehicle access

What are the part numbers and build quality details?

This Motoforti resistor corresponds to a range of OE reference numbers, ensuring compatibility with original equipment specifications. It combines metal and plastic components to resist wear and scratching while providing stable electrical performance.

• Matches OE numbers: 4P1618, 4P1787, RU841, 20602, 20467, 20586, 68079480AA, 68029736AA and others
• Constructed of metal and durable plastic for longevity
• Sold as a single blower motor resistor unit

Who this part is for: If you own one of the compatible Chrysler, Dodge or Jeep models and are experiencing limited fan speeds, intermittent blower operation, or a non-working HVAC fan, this Motoforti blower motor resistor is a cost-effective service part. It suits vehicle owners who prefer a plug-and-play replacement, independent mechanics handling HVAC repairs, and fleet maintenance teams needing a reliable aftermarket alternative to restore climate control performance.
