Hi guys new here and would really appreciate your help. My 05 1.6 overheated a couple of weeks ago so I let it cool then topped up the coolant and limped home to have a closer look it was then that I noticed that the radiator fan wasn't kicking in and thinking on it hadn't for a while, even tho the gague was reading near 95-100 (Usually it'd kick in at 90ish). So anyway I checked the fuses under to the right of the steering wheel and they seem fine. Changed the thermostat- no fan. I just changed the temperature sensor and still no fan! What am I missing? Strangely there is a wire connector that doesn't seem to be connected to anything but I cant find where it should go (may or may not be relevent) any help greatly appreciated.

Any fuses for a radiator fan will be in a fuse box under the hood, not inside the car. Typically it's a large 40 amp or perhaps a 30 amp fuse. If it's blown, spin the fan by hand to feel if it's tight. That will blow the fuse. If it spins freely, check if your car uses an electronic module for the relay. Those are used to allow the fan to be run at varying speeds as needed but being full of electronics, it's common for those to overheat and short.
