The slow speed cooling fan should trip on at 104C if you can get it there. Try a brisk run for a couple of miles and immediately park up with the engine held at a fast tickover. Also worth running the Demist button slow fan test. Come back here with the results.

I'll do that tomorrow. I can park up on my way to the motorway.
Just to be clear. I haven't run her for a few days so it was a cold start.
I waited for the thermometer to reach 9pm and read the display. It was 84. I pushed the accelerator and it revved about 3000 before I could find the point to settle it at 2000. I watched as 84 dropped to 83.. .....82.... 81 etc. over about 2 minutes.
I then called it a day and went in.
On past listening I think the fan is running but will check again.
Thank you TC
