Standard Ignition HVAC Blower Motor Resistor P/N:RU-799
Regain control of every fan setting with the Standard Ignition Blower Motor Resistor (MPN RU-247), the front-mounted resistor that meters current to the HVAC blower for its range of variable speeds. This blower motor resistor for the 1991-1997 Toyota Previa installs as a direct-fit replacement. See the Buyer's Guide tab for the full engine-level fitment.
A worn resistor often shows up as a blower that only runs on the highest setting or that loses one or more intermediate speeds. Diagnose the cause before replacing.

This part cross-references / interchanges with the following part numbers:
What does this blower motor resistor do?
It meters current to the HVAC blower motor to provide its range of variable fan speeds. On many systems the highest speed bypasses the resistor, which is why that speed can still work when the resistor fails.
Does the RU-247 fit my 1991-1997 Toyota Previa?
It is a direct-fit replacement for the 1991-1997 Toyota Previa. Check the Buyer's Guide tab to confirm the engine-level fitment for your specific vehicle before ordering.
Why does my blower only work on high speed?
If a failed resistor is the cause, only the high setting works because it often bypasses the resistor. Diagnose the circuit first, since wiring or the switch can cause the same symptom.
Where is this resistor located?
This is a front unit that mounts in the HVAC system's blower circuit. Consult the vehicle service information for its exact location and the correct removal procedure.
What numbers does this part interchange with?
It cross-references RU947, JA1357, BR157, 1468109570, and 8713895D00. Match your original part number or the vehicle application to confirm the correct replacement.
