my girlfriend has just bought a 2003 street ka 1.6 8v duratec and when she arrived in it i noticed that the cooling fan was going flat out and i thought this was a tad strange but let it go thinking it had just being on a long trip to mine, ( looking on here seems like this is a problem with them ) anyway a few weeks went by and she had just set off to go home and when sat in some roadworks the warning light came on for overheating followed by steaming from under the bonnet. i recovered the car back to mine and as im a mechanic i was sure of the circulation from the water pump was good and as i had heard the fan working i knew it wasn't that so i replaced the thermostat. i got it replaced and had all the air locks removed and had good circulation again all hoses hot and running it upto temp waiting for the fan to cut in. 15 mins passed and no fan 20 mins later the warning light came on to say overheating and i check for a feed at the fan and it has no feed. no idea why it has decided to not work. by this time it was dark outside so i had a quick check of the fuses under the steering column and they are all alright. so
1. can any body tell me where the radiator fan fuse is
2. where the relay is
3. is there any common wiring faults with them
4. is there only one temp sensor on the system on top of the thermostat housing??
5. what is the resistor for in the fan housing at the bottom of the radiator??
any help would be great thanks
