Had them for installed for almost 2 years.

I unhooked them last December for my heads/cam swap.

They never turned on after the swap but I assumed b/c the cold whether kept it cool.

Today finally got up to 90*. I was jumping a buddies truck and when I got in the temp was climbing at 200-210.

They are hooked up correctly......so could it be the control/relay box or fuse? How would I test to find out?

The box does not look to be melted

 

Check for power at fuse if good check fuse if good check power at relay if good check power at connector for fan. You can run jumper wire at relay wjen pulled to check if fans are good could something easy
