Audi 100 c4 electric engine fan not working

[Malbec]

Hi all,

Been a member here for about a month and enjoyed reading. I have a 1991 audi 100 2.3 c4 auto. I want to make this car my daily driver as it is in good condition and I believe (hope/pray) that these are reliable cars.

Recently my electric rad cooling fan has stopped working. My car has a main fan which is viscous, so that works, but the electric fan does not cut in, even when temp gets to over 110c. It used too, but has suddenly stopped working. I have removed the fan and discovered it works from a battery and that there is no current from the supply lead. I have checked the fuse in the dash side, all ok. But I believe there is another fuse under teh dash, but I cannot find it? Hope someone can help, I am due to go on a long journey in this car soon, so i need he fan working.

Cheers,

John
