Standard Ignition HVAC Blower Motor Resistor P/N:RU-55
Standard Ignition RU-455 blower motor resistor for the 2004-2009 Toyota Prius controls the speed of the blower motor in the A/C and heater.
A blower that runs on only some speeds, or not at all, can mean the resistor has worn out. A tired blower motor is another common reason for a misbehaving fan, so these signs alone don't prove the resistor is the problem.
Made specifically for Toyota applications, this blower motor resistor fits the 2004-2009 Toyota Prius, and the car takes one.

This part cross-references / interchanges with the following part numbers:
Is the Standard Ignition RU-455 the right resistor for a 2004-2009 Toyota Prius?
Yes. The Standard Ignition RU-455 is listed for the 2004-2009 Toyota Prius.
Does the RU-455 come with a wiring harness or mounting bracket?
No. The Standard Ignition RU-455 is the resistor only. The wiring harness, mounting bracket and hardware are not included.
How many speeds does this HVAC blower motor resistor support?
This resistor is listed as a 3-5 speed unit at 12 volts. Its rectangular connector has two cavities, and the resistor has five male blade terminals.
Why does my blower only work on certain speeds?
A worn resistor can leave the blower working on only some speeds, or not at all, and the connector may show burnt or melted terminals. A shop can test the circuit to be sure.
