Air blower question ford focus 2001 model

Boy am I glad you asked this question. I have the same problem.

Does you air conditioner stop on position 4 yet work on 1,2, & 3?

No mine works in position 4, does not work in position 1,2 and 3

I hope we find the same solution to a slightly different problem. Staying tuned.

My Haynes manual suggests it can be seen once the blower motor is removed

i) For safety, remove the negative terminal on the battery. (note that a bit further down I suggest testing by shorting across the fuse - the power needs to be one for this)

This will remove the power from the radio which will then need the security code to make it works again. Removing the power will also reset your engine management system. The car may then appear to be a bit 'lumpy' for a few miles while the engine management re-learns the optimum setting(s).

ii) Remove the 3 screws securing the lower passenger side foot-well trim and withdraw the panel.

iii) Remove the 3 screws from the glove box hinge and remove the glove box. Firmly press both sides of the glove- box to distort the plastic to enable removal.

iv) Undo the securing screw and detach the ventilation hose from the blower motor.

v) Unplug the motor's electrical connector and undo the three screws holding the motor in place. Remove motor.

vi) The motor control resistor can be can be removed by undoing the screw at one end of the assembly - pull the resistor out of the housing.

I have successfully performed thermal fuse surgery on two similar assemblies - although not on my focus.

Below is something I posted a year or two back with new edits

The speed of the fan in the first three positions is controlled by a bank of resistors which are relatively large and get hot. The thermal fuse is in series with these resistors and physically almost touching them. When the fuse blows the first three position don't work. In the final switch position the battery voltage goes straight across the motor, bypassing resistors and thermal fuse network, hence it works.

The resistor and fuse assembly is usually mounted in the blower motor air stream and I believe that you can get to the resistor assembly by removing the blower motor in the Focus. Release the glove box by flexing the plastic sides (a _tiny_ bit of force may be required). The glove box then hangs out of the way and you can see the blower motor and fixings.

The fuse is a two legged device which when it reaches a preset temperature blows permanently open circuit.

I would assume that the way the module is constructed that the fuse alone isn't a replaceable part and that a dealer would charge for the whole module. However it is a do-it-yourself fix if you can find the motor 'resistor module' and have some basic electrical soldering capabilities.

In the UK the a replacement thermal fuse (for the do-it-yourself repair) can be obtained quite cheaply (0.5 GPB or less than $1 US) from electronic component stores.

or

When buying the replacement fuses the one you want is probably towards the higher end of the temperature range (150+ degrees C).

Before replacing the thermal fuse check it with a meter to see if it open circuit or temporality short across it to see if the motor works on the lower speed settings.

Despite the warnings about not to solder to the leads of a thermal fuse I've successfully used a high wattage soldering gun and _quickly_ soldered at the ends of the leads. Obviously as it is a one time thermal fuse leaving the soldering iron in contact too long will heat up the whole device to a temperature where the fuse blows. As they are cheap it may be worth ordering a couple - just in case :) You could attach a crocodile clip or bulldog clip as a heat-sink to the body of the fuse while soldering to reduce the heat build-up.

Cut out the old thermal fuse but leave about quarter of an inch of the lead on each side that is crimped to the terminals on the assembly. Leaving a bit of the old lead in place will make soldering the new component easier. Soldering to the terminal post is difficult unless you can clean it up with a small file.

(It doesn't matter which way around the fuse is fitted -it isn't polarised.)

The problem may have been caused as a result of water getting into the system and the blower motor not running as smoothly as it should. On previous cars where I have fixed identical problems the motor shafts were rusty and some lubrication (ONE DROP of engine oil from the dip-stick) was applied to the motor shaft bearing area.

Before attempting this repair check out the newsgroup archives at

Type 'thermal fuse blower motor' into the search box (without the quotation marks).

The advice given for other cars is valid.

Blower ONLY working on position 4 = probably thermal fuse.

Blower working on 1,2 ,3 but not 4 = the switch may be faulty.

In a UK Focus to remove the blower motor switch:

Disconnect the battery (for safety reasons)

Remove the radio/cassette. If you disconnect the battery or radio make sure that you have the 4 digit security code (and instructions) that you need to enter to make the radio work again. See

Undo the four securing screws from inside the radio/cassette player aperture, then carefully unclip the heater control panel from its three retaining clips in the fascia.

Disconnect the wiring connector from the switches as the control panel is being removed.

Circuit and thermal fuse data (fuse data/prices is a year old)

need your email address and i'll send a picture snipped-for-privacy@hotmail.com

if this is a uk focus and it's differant from usa why don't you use the COUNTRY SPECIFIC UK FORUMS or at least have the courtisy to specify that you're UK. I really don't think you want someone going to alot of trouble to help you when the info going to be wrong. I know what you're going to say that this is not a USA only forum. However for you less dease forum flunkies COUNTRY SPECIFIC is a helpful tool to getting info that is SPECIFIC to your country

This is not an Internet forum, it is a newsgroup.

There is no UK Focus newsgroup.

By casual observation, European posts here outnumber US ones by about 3 to
