Motoforti Blower Motor Resistor for Grand Cherokee 2011–2013 — Metal Direct-Fit, Automatic Temperature Control

Motoforti's blower motor resistor is a direct-fit replacement that restores variable fan speeds for Grand Cherokee and compatible Chrysler/Dodge vehicles equipped with automatic temperature control.

If your HVAC fan is stuck on one speed or has stopped responding, the blower motor resistor is a common, inexpensive component to check and replace. This Motoforti unit is built from durable metal and plastic, matches multiple OEM part numbers, and installs without specialized tools as a straightforward plug-and-play repair.

What vehicles is this resistor compatible with?

The Motoforti blower motor resistor fits a range of Chrysler, Dodge and Jeep models that use the specified OEM numbers. It is intended for vehicles equipped with automatic temperature control where the original part numbers align.

• Jeep Grand Cherokee 3.6L (2011–2013)
• Chrysler 300 (2.7L, 3.5L, 3.6L) across 2008–2013 and 2018
• Chrysler Pacifica 3.6L (2017–2022) and Town & Country variants (2008–2016)
• Dodge Charger, Durango, Grand Caravan, Magnum and Voyager models listed by year and engine in fit notes

How does this part restore HVAC performance?

The resistor controls the blower motor’s multiple speed settings by providing the appropriate electrical resistance for each fan speed. When the resistor fails, some or all blower speeds may stop working; replacing it re-establishes full speed range and reliable airflow control.

• Replaces worn or broken resistor that causes fan to operate only on high or not at all
• Matches OEM electrical characteristics via listed part numbers for proper operation
• Durable metal and plastic construction resists wear and heat cycling

Is installation difficult and what tools are needed?

Installation is designed to be simple: the Motoforti resistor is a direct replacement that connects to the existing blower motor harness. Most installations require basic hand tools and minimal disassembly of the lower dash or glove box area depending on the vehicle.

• Direct-fit design — no modification required
• Typical installer tools: screwdriver or socket set for access panels
• Plug-and-play electrical connector for quick swap-out

Which OEM numbers and features should I check before buying?

Confirm compatibility by matching the original resistor’s part number to one of the listed equivalents from Motoforti. The product lists several OE numbers and emphasizes an easy, direct replacement with metal body for longevity.

• Referenced OE numbers include 68079480AA and 68029736AA among others
• Made from metal and plastic for abrasion and heat resistance
• Sold individually — package contains one blower motor resistor

Who is this for: This Motoforti blower motor resistor is intended for DIY mechanics and professional shops working on Chrysler, Dodge or Jeep vehicles in the listed years and engine variants. If your cabin fan is intermittent, stuck on a single speed, or not working at all, and your vehicle matches the OE references, this direct-replacement resistor offers a cost-effective way to restore HVAC fan control without complicated wiring or programming.
