Drop by your local Ford/Mercury dealer & ask for a blower motor resistor, and ask if Ford is doing anything to help owners with this problem, as it well known that water getting in to blower motor is causing this. You might want to call a local autoparts store for their price on it before you go to dealer, just in case of big price difference.

My mother in laws 2002 century blower only works on high..


It is not the blower motor.
On the 2002 model, I am showing an HVAC control module and a blower control processor. The control module handles the temp control and blower speed, and the processor contains the resistor for slower blower speeds.
Which component did you replace ?

Heater blower stopped working?


Hello,
You may want to try your fan on all speeds. If it will work on high, you have a bad resistor for the fan motor. ( high speed doesn't go through the resistor ).
If it doesn't work on any speed, I would check the following;
1. Make sure the fuse isn't blown for the fan blower motor.
2. Check, or have checked the wires between the fan control switch and the fan blower motor.
3. Have the fan control switch checked.
4. Have the fan blower motor checked.

I hope this helps you.

Blower motor is bad. Resistor controls speed. Motor is so worn out that it will only turn when set on high. Best to replace it before it burns out something else due to the high current draw.

Problem with blower motor is the blower motor resistor. They are usually located next to the blower motor, a couple of screws and a couple of plugs and your done. Autozone sells them for around $30 each. Wipers you may want to check for relays under the hood in the fuse block. There may be 2 relays 1 for low and 1 for high. I have switched relays from other working accesories and got wipers to work. Sometimes bad connection.

Hello,

The blower motor, as you have probably seen, is under the dash on the passengers side. While in Park with the parking brake applied:

Turn the Key On with fan blower set to High. Locate the blower motor and wiggle the electrical connector. If this brings the blower motor to life, a new blower motor is needed. This, if applicable, is a common failure that matches your symptoms. The new blower is simple to replace, although it is never fun working under the dash.

If you have a 12 volt test light or DVOM (multimeter) you can check for power at the electrical connector. You should have battery voltage (12+) with the blower set on high. Always use a known good ground when testing for power. If you have power (key on, set to high) and no blower operation the blower motor needs replacing.

The resistor you replaced is a very common failure on these.

Give me an update.

Blower motor speed


The resistor is under the dash on the passenger side. You'll have to remove the protective accessibility hatch first & it will be right underneath there. You'll probably need a 3/4 wrench to remove the 2 bolts that hold it in place. If you replace the resistor & it works for a while then burns out, then it's your blower motor drawing too much voltage & that may need be the next thing to replace so it's like catch 22.
