Take command of every cabin fan speed with the Standard Ignition HVAC Blower Motor Resistor RU-441. It is a direct-fit replacement for the listed applications: the 1995-1996 Ford Contour, the 1995-1996 Ford Mystique, and the 1995-1996 Mercury Mystique (All engines).
The blower motor resistor sits in the heating and air-conditioning circuit and adds calibrated resistance to the blower motor's feed, which is how the climate control produces its lower and intermediate fan speeds. When the resistor fails, the blower commonly runs on only one setting (often high) or drops certain speeds entirely, since those steps route through the resistor.
- Fan-speed control: supplies the resistance steps the system uses for the low and mid blower settings.
- Signs it may need replacing: blower works on some speeds but not others, or only on high.
- Direct-fit: a direct-fit replacement for the listed applications.
Diagnose the cause of a blower-speed problem before replacing — if the resistor is the fault, RU-441 replaces it. Interchange: Manufacturer part number RU-441.
Frequently Asked Questions
What does the HVAC blower motor resistor do?
It adds calibrated resistance to the blower motor circuit, which is how the climate control creates its lower and intermediate fan speeds.
Which vehicles does the RU-441 fit?
It is a direct-fit replacement for the 1995-1996 Ford Contour, 1995-1996 Ford Mystique, and 1995-1996 Mercury Mystique (All engines). See the Buyer's Guide tab to confirm your vehicle.
Why does my blower only run on high speed?
That is a common sign of a failed blower motor resistor, since the lower speeds route through it. Diagnose the cause first; if the resistor is at fault, this part replaces it.
Is this the same as a blower motor?
No. This is the resistor that controls fan speeds, not the blower motor itself. If the fan does not run on any setting, check the motor and related wiring too.
What is the manufacturer part number?
The manufacturer part number is RU-441 from Standard Ignition.
