Talking 2006 Jeep Grand Cherokee Radiator Fan Fuse Blown

Hello I'm a new member and I have a question. I noticed the 50 amp fuse was blown for the radiator fan. I replaced it and had a fan and ac for about 5 minutes and it blew again. I have had issues with my enginre overheating and that is how I found the fuse was blown and I had no fan. Could the radiator fan relay switches be dong this to the fuse?

I would expect a wireproblem. Check the wirebundle if its not touching some metal part.

Re: 2006 Jeep Grand Cherokee Radiator Fan Fuse Blown

Just to explain it maybe better, check the wires for chaved isolation. The fact that the fan runs for some time and then blows the fuse, makes me think that a wire is shaved through and due to vibration or the movement of the engine makes contact with some metal part and blows the fuse. A bad fan will also increase the current draw, but i wonder if it would go that high to blow the 50A fuse.
