All, 2005 MPV good car and last week 30 amp fuse blew. Replaced it and 1 week later blew again. How do I service this? Also does any one know where to buy a breaker (like in a house) to replace the fuse while I test? ~ 4 dollars a fuse and could be expensive.
You might have a short to ground problem. the circuit is complete from the battery to ground. Check the wire from the fuse to the load, and chances are there's a spot in it where the wire is touching ground.

Many cars have the cooling fan on a thermostat or time delay, to allow it to run for a short period of time after the engine turns off, to cool the engine off. You may have just never noticed it before. So I wouldn't worry about that. Your real problem is the blowing fuses, apparently you have a short somewhere in your wiring. Putting in bigger and bigger fuses is a great way to set fire to your wiring harness. It's possible that the wire is pinched or chafed somewhere, and perhaps when you hit a bump just right, it touches and shorts. You may have to take this to the Chevy dealer or a GOOD independent shop to have them chase it down. Unless someone out there knows exactly what this is, it could be a tough one to find.
My car stopped running without any warning, its a 2005ford focus, 2.0 and the 20 amp fuse for the engine management keeps blowing, it's number 9 in the panel and I have replaced it twice, both times it blew again, any tips? Also the odometer reads ------ and that's it.
Obviously a short somewhere. Check sockets for corrosion, rust etc where current could be traveling across, as well as take a look at wiring into rear if you can get to it. One other thing you could try to isolate, would be to try one bulb in at a time, perhaps one will cause fuse to blow & other won't, which will give you a reference point to start looking.
it sounds like when the cat was changed they have trapped a wire or just moved one over a bit and its rubbing think about what items this 30amp fuse is protecting are any of the items close to the exhaust or around that area, i dont see the aftermarket starter doing this after 2 years hope this is helpful regards JR
that fuse feeds power to fuel pump relay circuit that feeds pump could be defective pump,or damaged circuit wires that shorts out! and not a good idea to put higher fuse in circuit could cause more damage to circuit! but i know when your stuck, u do what it takes,so inspect circuit related to fuse,
If your phone is drawing more amps than your fuse is rated for, then the diagnosis is correct. If you are plugging it into your auxiliary power port try increasing the amp rating of the fuse. IE; 15amp to 20amp
