Can anyone help? My radiator fan is constantly on soon as battery is connected, even if ignition isn’t on? I’ve changed coolant temp sensor and it’s still happening? Cheers

I had a similar problem with a Saab 93 a few years ago. It turned out to be a broken wire in the wiring loom (extremely difficult to find) The battery would be completely drained overnight and unbelievably it was affected by temperature. It may be worth checking the wiring circuits just in case
