thanks dave, ive checked and my arrangement looks right. ive uploaded a rough drawing of what i have.
ive just found if i have one switch connected to the toggle as soon as i turn ignition on the fan comes on, fuse doesnt blow and toggle does nothing. when both switch wires are connected fans come on then fuse blows.
thanks again, chris.

Your drawing is a challenge to read because the resolution is very low.

I see a toggle switch that has only one wire connected. The other side of the toggle connects to (86) the relay coils. Ok.

But wait... your battery feeds (30) a contact, but the other side of that contact (87) connects directly to ground. You have to know this is a direct short to ground as soon as the relay energizes.

30 & 87 are the —| |— contact <--between the battery and fan
86 & 85 are the coil <--if 86 connects to your toggle switch (and temp sensor), then 85 goes to ground.

Wire them according to my drawing. - Dave

Sometimes I have to laugh at myself, I've actually marked the drawing wrong. Fan wire is going to 87 and ground is going 85.
All sorted now, turned out I had a faulty toggle switch. Changed switch and everything works as it should.
Starting to think it might be time for a break once this is sorted. Brain is fried haha.
Thanks again Dave and others.
