Dear All,

I have a 2002 1.6 Ford Focus and the heater blower/aircon will not work on settings 1-3, on setting 4 the blower works but the Air Con light goes out. I have spent hours going through all of the posted help and done/checked the following:

1. Checked all fuses and relays - all fine;
2. Replaced the pollen filter, Blower Motor Resistor and Dash Switch (new parts from Ford);
3. Removed the blower motor, bench tested and checked the bearings - all fine;
4. Checked the loom between the switch and the resistor - although all of the wiring is good and the connections are good no power to the resistor from the switch on settings 1-3, there is power to the dash switch;
5. When the engine is cold the cooling fans dont come on, when the engine is at running temp both fans are on together;
6. When the engine is cold and the air con button is pressed the compressor clutch does not engage, however when the engine is at running temp the clutch engages and releases at the opperation of the dash switch in possitions 1-3;

Questions:

1. Should the Air Con light go out on switch possition 4?

2. What could the fault be? Is there anything I can check before a spend a fortune on an auto electrician - ford main dealer mechanic inspected the car for about 30mins and simply shrugged his sholders and said he had no idea what the problem could be!

Please Help
