Question about 2000 Jeep Grand Cherokee
Did you check the temp sending unit? That tells the computer what the temp is and the computer then triggers the relay. Also, hot wire the fan motor and make sure it runs when it has power.
As far as the radiator "busting open" if it actually did that and didn't just develop a leak, it may indicate a head gasket failure pressurizing the radiator far more than it's normal capacity.
