My 2000 Kia Sportage keeps blowing fuses intermittently. The Auto electrician said that there was nothing he could do until it blows completely/ most of the time. Can anyone help?

You need to visit or have a visit from a competent auto electrician for this fault.

My experience with a kia sportage is that the big fuses are simply inserted to the fuse box located in front of the battery at the engine bay. The plastic holders gets brittle over a span of time and due to the heat inside the engine bay. Most often the fuse loosens up and causes fuse blow out. I had 4 successive fuse blows in 2 months time that i decided to change the whole fuse holder with a new one. It Worked

Have the battery checked first (load tested).

you have faulty brake light switch or one of brake light bulb sockets or wiring have a short.

the problem could be coming from the indicator relay as doesn't blow fuse instantly, try with the 4 way flasher on and see if relay get over heated , electronics work in weird and varied ways ,most fuses supply power to more than one function , check what the other function's run from the problem fuse , this will , hopefully explain why the engine cuts out,

which means that whatever that fuse is for, its shorting out

well, blowing fuses is caused by a short, has the vehicle had anything done to it before the fuses started blowing ??? and what fuses are blowing, if it is the main fuses that are 200 amp, then it could be caused by faulty wiring, or bad earth.......trust me if it is the 200 A fuse that is blowing, you will be very happy that it is, because if the manufacturer did not put that fuse there, you would be facing a vehicle fire.....i would trace the fault, or have an auto-electrician diagnose for you

Possibly a bad ignition switch unplug the harness under the dash follow it from the ignition to the plug (about 8" from ign) unplug it put a fuse in and see if it blows.

Hope this helps!
