Standard Ignition HVAC Blower Motor Resistor P/N:RU-427
Help keep every fan speed working with the Standard Ignition Blower Motor Resistor RU-554 (also written RU554), a direct-fit replacement for the 1998-1999 Acura SLX, 1999-2002 Isuzu Trooper, and 1999-2001 Isuzu Vehicross. This resistor steps down current to the HVAC blower motor to set the lower and mid fan speeds; when it fails, the blower often runs only on high or drops certain speeds entirely. If a failed resistor is the cause, RU-554 replaces it.

This part cross-references / interchanges with the following part numbers:
What vehicles does the RU-554 blower motor resistor fit?
It's a direct-fit replacement for the 1998-1999 Acura SLX, 1999-2002 Isuzu Trooper, and 1999-2001 Isuzu Vehicross. Check the "Vehicles it fits" section to confirm your vehicle.
Is this the right blower motor resistor for a 1999-2002 Isuzu Trooper?
Yes. RU-554 is listed as a direct-fit blower motor resistor for the 1999-2002 Isuzu Trooper. Check the "Vehicles it fits" section to confirm your vehicle.
What does an HVAC blower motor resistor do?
It steps down current to the HVAC blower motor to set the lower and mid fan speeds, giving you variable blower speed control for the heater and A/C.
My blower only works on high speed — could this be the cause?
A failed blower motor resistor commonly leaves the fan working only on high or missing certain speeds. If diagnosis confirms the resistor, RU-554 replaces it.
What interchange numbers does RU-554 replace?
It cross-references 8970831360, 8970831361, 8972345450, RU1247, JA1294, and BR457.
