  • my fan is always on and at higher speed, thermostat is replaced but no changes

  • Hi Michael, I had exactly the same issue with my Astra J 2012 sounded like it was going to take off. I put mine on a diagnostic computer and it turned out to be the thermostat housing which has an electrical connection on it, it was not not the thermostat itself, I replaced it and it’s been fine ever since, Think it cost about £45 but that was about 5-6 years ago.
    Hope this helps.
