Location of Fan Blower Resistor
Help. I can't find the fan blower resistor on my 99 Mercury
Mountaineer with climate control. I bought the replacement part and expected to find it in the usual location(s)--in the ductwork ds of the fan under the hood. Well there is a lot if aluminized insulation on the box but no wires going in that I can see. So I took the glove compartment out thinking it might be in the passenger compartment--no joy. Anybody know the location of this part? Thanks, Jerry |

It uses a motor controller which is significantly more expensive. If you're looking under the hood at the blower motor the controller is at about 5 o'clock. There's a black wireplug that goes into it. |

On the 1998 Mountaineer the Blower Motor Switch Resistor, if that's what
you're referring to: The heater blower motor switch resistor has the following features: 1. - The assembly is located on the evaporator housing in the engine compartment. 2. - Three resistance elements are mounted on the resistor board to provide four blower motor speeds. 3. - Depending on the heater blower motor switch position, series resistance is added or bypassed in the blower motor circuit to decrease or increase blower motor speed. 4. - An overheating protective device (thermal limiter) will open the resistor coil circuit when the temperature reaches 121ºC (250ºF) interrupting the blower motor operation in all speeds except HI. 5. - The thermal limiter cannot be reset and is not serviceable.

Thanks Steve,
That was the problem. The dealer sold me a resistor and I needed the controller. They should have the controller for me today and I can see where it goes.

OK. Followup. It's a little difficult to get to. The screws that
hold it in are sheetmetal screws and take an 8mm socket. I removed what I think is the cruise control actuator (one 10mm head screw) and used a 1/4" drive ratchet to remove the outboard one--slow and tedious. I used a replacable tipped screwdriver adapted to the 8mm socket with about 10" of extension to reach the inboard one pretty easily. You'll need a flashlight or shoplight even in good lighting. Fan works fine now. (symptom was no controlled speeds, only high and off) --Jer No Twilight wrote: > Thanks Steve, > That was the problem. The dealer sold me a resistor and I needed the > controller.
