Well after starting on the car at 8.30am yesterday have only just finished it (well this avro anyway) the thermostat is working, fan is NOW kicking in as it should now it's been wired back in again, my parents drove all the way up from Portsmouth to Essex to see what was what with it as we were both (me and hubby) getting stressed with it loads.
Car turns out to be just a hot runner and fan kicks in at 3/4 were just so relieved to now know that it's all fixed and done and the travel down south will be fine!
THANK YOU to those that gave us help too on here about it.....
