Blowing what fuses? Do you have a multimeter? Is it when the vehicle is running? or not running? Jump start the vehicle lately? Install any aftermarket gear like lights or stereo?

    My best suggestion would be to disconnect those devices where you can and reattach 1 by 1 until you see fuse blow again. Then you can read the load its pulling on each system. Especially if this is a new condition it sounds like a ground which is normally a wear in the insulation somewhere.

Hello,

Thanks for using FixYa.

If fuses keeps blowing, you definitely have a short in your electrical system. Putting in a new fuse will be useless until you isolate the short. You need to get yourself a tester to isolate the short. If you are not sure what to do, i suggest that you go to the nearest auto shop and have an electrician isolate the short for you, isolating a short is a 30 minute job for an expert.

I hope this helps. Thanks and good day.

I have a 2004 Pontiac Grand it keeps blow the ignition fuse now my dash and brake fuses blow! I use atuo door lock blows a fuse where do I start??


Remove the fuses to the circuits that blow. Then one at a time, install a fuse, turn any component on and see if it blows the fuse. Have you had an accident recently ? If so, maybe a wiring harness has been damaged and causing your problem.

Could a 1000 amp battery blow fuses in a 1999 blazer


Likely there is a blown fuse but a battery won't blow a fuse on its own. Change any blown fuses and if that fixes the issue and the fuse doesn't blow for awhile then your ok but if the fuse blows quickly then you have an issue with the electrical system and you need to take it to a shop

Hi, I own a 96' 4x4 3.4L Ext. Cab T-100 and it WILL NOT STOP BLOWING THE EFI FUSE! Before, it seemed as though the fuse blow time to drive ratio got smaller as the engine got hotter. In otherwords it...


possibly you have a schafted wire in the wiring loom at the fuel injectors, or at the fuse junction box. (short) hit a bump just right and it shorts out blowing the fuse.

Four Wheel drive not working. Blows fuses.


Hi:
Your four wheel drive push button system has only 3 components, so there is a way to narrow down what is blowing the fuse:

the system includes the push button panel and indicator light, the shift control module, and the shift control motor.

The shift control motor is the only part that can draw enough current to blow the fuse. If for some reason the transfer case is jambed up, that could blow the fuse too...So if you are planning on attempting repair yourself:

first, unplug the connector off of the shift control motor, and see if the fuse still blows.. if not, then remove the shift control motor from the side of the transfer case and plug it back in to the harness and see if the fuse blows. If so, then the shift control motor is bad, if the fuse doesnt blow then you need to check out your transfer case.

Toyota Camry 1994 Main Fuse keeps blowing


-if your fuses are blowing
-the problem is in the wiring
-because if too much amperage flows through the fuse will blow
-there's probably a short to ground somewhere or high resistance after the fuses causing it to draw more amps

ECM BATT fuse keeps blowing


That fuse provides power for the fuel pump. Either your fuel pump is blowing the fuse or there is a shorted wire.
