Cooling fans, offside not cutting in.

[S6 Devil]

The offside cooling fan is meant to cut in first according to the bible. Mine doesn't seem to be working. The nearside cuts in, although I'm not sure at what temperature. The dash was reading 100c which it hasn't done for a long time. I've swapped the relays over but still the same. Any ideas?

Had the same with mine and checked both fuses and swapped relays. Dom at TVR Power advised cleaning up the connections at the fan end (white plug) as these are prone to corrosion. Job sorted!
Mine is a T350.

Check the earth for each fan.

I'm a bit of a numpty when it comes to electrics, how would I doo this?

Try unplugging and plugging back together the connector next to the fan, a mates T350 had this problem and it was a poor connection on that plug, playing around with the connector would get the fan to come on.

Had same problem couple of months ago, check fuse, relay etc. Replace the temp sensor and everything worked again.

Just a quick update, it was the fuse that was knackered. Thanks for the advice!

Should both fans cut in at the sometime?

No. On mine the offside comes on first at around 90 I think. Nearside at 98
