i've try to plug the fan right to the battery on it work
what could be the trouble

Try using the fan switch from the Festiva engine.

He said the fan still doesn't come on after unhooking the temp switch. Wouldn't that point towards a relay?

Yes, or something besides the temp switch.

if my solder to the fan switch arent good ,do the ground is no good if i unplug it

The fan should run constant if there's no connection to the switch. Its a fail safe thing.

trouble find it was the conector on the fan was loose and the relay to was loose
