Use jumper wires from battery for voltage and ground, use 30 amp inline fuse. Run wires to fan connector. If fan runs ok w/o blowing the fuse, the problem is in the wiring circuit to the fan. If the fuse still blows, something wrong with the fan. Just my opinion.
The cooling fan motor is likely drawing to much current because it is worn out.

You have a large wire that powers the ECM, it has rubbed through and is grounding out and blowing the fuse, locate the power source for the fuse under the hood, then look for damaged wiring, check places were the wires touches the body, it will not be easy, it takes time and a keen eye.

The fan may run with jumper wires but if it''s blowing the 30 Amp Maxifuse it's needs a new or used fan motor.It's pulling too many amps.I have almost never seen a fan relay concern.Only other thing you may check is the wiring down near the fan shoud I have seen the 2 wires get loose from the conduit & melt onto exhaust manifold.Hope tHis Helps

Sounds like you have short to ground somewhere, I would check the wires near the horn itself and if they are ok check the clock spring.

More than likely the fan motor its self is short to ground try to unhook the wires to the fan motor and install a new fuse and then turn the fan on with the wires removed and if the fuse is still good you know it is the fan motor its self
