Fixed

 

About the only other thing I would know to check is the connections for poor contact & maybe corrosion??
Sorry it's probably no help to you.

 

I would start with seeing if the fan switch is still grounding the second time.

At the time the fan should kick on again, pull the wire and ground it. If the fan runs, the circuit is fine. Test for resistance to ground through the switch (at same temp, no fan on), if a multimeter shows noting (open circuit), the switch is bad.

 

Sounds to me to be the relay!

 

I never had any luck with the fan switches, from cheap to hypertech they all were crap.

I installed a seperate fan controller from Flex-a-lite and never looked back - it's been great for 3 years now, fully adjustable, manual toggle control options, always works like it should.

I think your better off starting a NEW thread, "On How To......." Or just do a SEARCH!!!!!!!
