  • 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.

  • Got astra 2011 1.4 . Left position lamp, left daytime running lamp, left low beam light error. But they do work sometimes. Switching both relays with each other. But no avail. 2011 doesn’t have daylight sensor in the windscreen at the top so it cannot be that. If it does where is it located?
