Product Details and Specifications
The RU-736 blower motor resistor from Standard Ignition is engineered to meet OEM specifications for HVAC systems in Land Rover LR3 and LR4 vehicles. It features a rectangular female connector with a single cavity, designed to interface with the vehicle’s wiring harness without additional wiring. The resistor supports 3 to 5 blower speeds, allowing for precise control of the HVAC blower motor. Four blade-type male terminals ensure a secure electrical connection, while the screw attachment method provides a firm and stable mounting solution. This part operates at 12 volts, matching the standard electrical system of the vehicle. Note that this resistor does not include hardware or mounting brackets, so existing components should be reused during installation.
Common Applications and Problem Resolution
- Restores blower motor speed control in Land Rover LR3 and LR4 HVAC systems
- Resolves issues with blower motor stuck on one speed or not working at all
- Fixes intermittent blower motor operation caused by resistor failure
- Eliminates overheating or electrical faults related to faulty blower motor resistors
- Improves overall HVAC system reliability and passenger comfort
Installation Notes and Tips
Installation of the Standard Ignition RU-736 blower motor resistor requires removal of the old resistor from the HVAC housing, typically secured by screws. Ensure the vehicle’s battery is disconnected before beginning work to prevent electrical shorts. The rectangular female connector should be carefully disconnected and reconnected to avoid damage to terminals. Since no wiring harness or mounting brackets are included, retain existing hardware for reinstallation. Verify that the resistor is securely mounted and that all electrical connections are tight before testing the HVAC blower motor operation.
