Bring your climate-control fan speeds back under command with the Standard Ignition HVAC Blower Motor Resistor RU-783 (also written RU783). A blower motor resistor steps the current supplied to the blower motor so the fan can run at its different speed settings; if a failed resistor is why your blower only works on high (or drops certain speeds), this unit replaces it. It is cataloged for front and rear HVAC blower applications on the vehicles listed below.
- Premium copper connectors: use copper electrical connectors for more precise resistance values, improving resistor performance and offering longer part life.
- Seamless HVAC integration: developed through the manufacturer's research and design process for a proper fit with the vehicle's HVAC system.
- Variable speed control: helps restore A/C and heater blower variable-speed operation to support HVAC performance and passenger comfort.
- Tested: undergoes extensive in-facility testing to confirm correct performance across conditions.

Frequently Asked Questions
What does the RU-783 blower motor resistor do?
It regulates the current sent to the HVAC blower motor so the fan can operate at its different speed settings for the A/C and heater.
What are common signs this resistor may need replacing?
Typical signs include a blower that only runs on the highest speed, one or more fan speeds not working, or no blower operation. Diagnose the cause before replacing.
Which vehicles does this resistor fit?
It fits applications such as the Fiat 124 Spider, Ford Explorer and Police Interceptor Utility, Jeep Commander and Grand Cherokee, Mazda, Mini, Nissan, Subaru and Toyota C-HR. See the Buyer's Guide tab.
Is this for the front or rear HVAC system?
This part is cataloged for both front and rear HVAC blower applications, depending on the vehicle. Confirm the correct listing for your vehicle.
What part numbers does the RU-783 interchange with?
It interchanges with 68314272AA, 64119240713, 64119286870, RU1472, 68059894AA, JA1986, BR683, AE9Z19E624A, GS3M61B15, N24361B15, 27761JE22A and 87138F4010.
