Question
the fan on the air conditioner has stopped working it blows on number 4 but not on 1 to 3, the light for air conditioner is on as normal

Answer
Sounds like the rheostat on the heater box
This controls the voltage to the fan in 3 6 9 & 12 volts stages.
When you set it to fan speed four this bypasses the rheostat and give the fan 12 volts to blow on maximum
Look under your glove box upwards from the passenger footwell and find the fan housing, it is likely to be cylinder shaped and houses the evaporator and heater matrix
Look for two or three wires that go in to a plug. On the Focus we have to remove a cover but it will be there somewhere.
Once you have found it it is a really easy job,

New one from Ford shouldn't be more than £ 20.00

Thanks

Expertise

Any question related to the function or malfunction of vehicle air conditioning excluding model specific problems with the heater controls. We are a UK based company and are unlikely to be familiar with the exact make and model of American vehicles. We will always at least try to guide the owner towards what the problem is likely to be in this instance We may struggle with none specific electrical issues related to the a/c without seeing it but it is likely we could narrow the problem down

Experience

Director www.chillywillys.org specialising predominantly in UK vehicles, fleet, rare and collectables. Although all a/c works on the same principal US vehicles have different controls and electrics. 12 years experience automotive and aircraft air conditioning. This is our sole source of revenue, we see lots of a/c issues that we are able to diagnose accurately mainly down to experience. UK have garages caught on to a potential revenue stream within the last few years but sometimes struggle with the problems as they don't see the issues that often........to be fair they could get their own back and ask me to change a timing belt ! Certain vehicles have known issues, we can help with that and also anything that is obvious to us but not necessarily to the bamboozled owner....... a/c is relatively new here and owners are catching on to maintenance but are sometimes still misguided by inexperienced individuals a bit timid to say' I don't really know
