your auxillary fan is not working. this fan is responsible for cooling the freon that is being circulated in your cooling system... check if there are any loose wires in front of the engine bay.
the auxillary fan is located right beside your radiator fan.
The most common cause for the cooling fan fuse to blow is a bad cooling fan motor. The failng motor will draw an excessive amount of current which actually heats up the fuse and melts it. Now if your fuse is blowing the instant the cooling fan(s) turn on, then that could be a "dead short". either inside the cooling fan motor or in the wiring going to it. Follow and inspect the wiring leading to the cooling fan motor. Check for any broken, cracked or burnt wires. If you don't see any of that, then you'll probably need a new motor. If you think you can tackle the job, most auto parts stores sell generic replacement cooling fan motors much less than you would pay at the dealership.
WARNING! - some cooling fan motors are easy to get to, and others are very difficult. Study yours carefully and then decide if you want to tackle the job before you start tearing it apart.
most likely the cooling fan has a short in it. disconnect the connector on the fan. If it doesn't blow now its the fan motor. If it still blows you have a short from the fuse to the motor. What this means is the hot wire is touching bare metal somewhere
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
Sometimes there is a separate switch to turn on the water pump. No water=no cooling. Check to make sure the cooling pads are wet! If they are completely wet and the fan is blowing it should cool.
