X AUTOHAUX blower motor resistor 68018105AA for Ram 1500/2500/3500 & Jeep — direct-fit, restores HVAC fan speeds

The X AUTOHAUX 68018105AA blower motor resistor is a direct-fit HVAC replacement that restores blower speed control for compatible Ram, Jeep, Dodge and Chrysler vehicles.

When the cabin fan in your vehicle stops cycling through speeds or only runs on high, the blower motor resistor is often the culprit. This X AUTOHAUX unit is built as a direct replacement for factory part 68018105AA and engineered to match the original electrical and mounting points, so installation is straightforward and you can return your climate control to normal without guessing which part you need.

Which vehicles does this resistor fit?

This resistor covers a wide range of Chrysler, Dodge, Ram and Jeep models across several model years. Always cross-check the part number and connector shape before purchase to confirm fitment with your vehicle.

• Ram 1500 (2013–2014), Ram 2500/3500 (2013–2018)
• Jeep Wrangler, Compass, Patriot (2010–2017 model ranges vary by year)
• Chrysler 200, Chrysler Sebring, Dodge Avenger, Caliber, Journey and ProMaster models listed in the fitment details

How does this resistor restore HVAC performance?

The resistor supplies the correct series resistance to the blower motor circuit so the fan runs at the intended speeds instead of just on high. It limits current to prevent motor overheating and ensures the vehicle’s blower control switch operates normally.

• Provides multiple stepped resistance values for speed regulation
• Prevents excessive current draw that can damage the blower motor
• Matches factory electrical connections for reliable operation

What materials and design features improve durability?

X AUTOHAUX constructs this resistor with corrosion-resistant wiring and durable housing materials to withstand under-dash temperatures and vibration. The connectors and insulated leads protect against moisture and corrosion that commonly degrade OE resistors over time.

• Insulated wires reduce the risk of shorting and corrosion
• Robust housing resists heat and mechanical stress
• Quality control for consistent electrical resistance values

How easy is installation and what’s included?

Installation is designed to be a direct swap for the original resistor—no modification or special tools are typically required. The package includes one engine cooling fan resistor and detailed fitment notes to help ensure you’ve selected the correct part for your vehicle.

• Direct replacement design for simple plug-and-play installation
• Includes one X AUTOHAUX 68018105AA blower motor resistor
• Fits original mounting points and connector type for most listed vehicles

Who this part is for: drivers and technicians who need a reliable, OEM-style blower motor resistor to fix erratic or reduced HVAC fan speeds on compatible Ram, Jeep, Dodge and Chrysler models. It’s suitable for DIY mechanics replacing a failed resistor beneath the dash, and for repair shops seeking a cost-effective, durable replacement part that matches factory specifications.
