A bad diode can cause the 10a fuse to blow. (it looks like a fuse that is located above and left of the AC fuse)
Your ugly stupid.
Compressor has seized.
not usually!!if fuse is blowing out check for short!!
Compressor may be locked up.
Find out why the fuse is blowing. You have a short or the circuit is overloaded.
If it blows the second you try to switch to ac it's probably the coil in the ac compressor.
if you are blowing fuses DO NOT ignore it. most likely you have a short between the fuse box and the ac compressor, you will probly have to rip out the dash to find it, its not easy, seriusly pay someone that knows what there doing to fix it.
If the AC stopped blowing air on your 2003 Toyota Echo, the blower fuse could be to blame. If the fuse is fine, it might be the blower resistor that needs to be replaced.
It is very common for the starter to be the cause of that fuse blowing.
Obviously, if any fuse keeps blowing there is a serious fault in that circuit.Take it somewhere they can fix it.
Assuming the heater works fine, you have a short, probably in the AC compressor clutch.
Something is causing the ac system to use too much current. Check the ac fuse and make sure it is the proper size. Unplug the connector to the ac clutch and see if the problem continues. If unplugging the clutch stops the fuse from blowing then either the clutch is bad or the ac compressor is locked up and will need to be replaced.
Wrong amp of fuse
Put a new fuse in. Turn on the ac, make sure you have enough freon to allow the PCM to engage the compressor. If it pops when the ac is turned on then the compressor clutch coil is most likely burnt. The fuse blows to keep the rest of the system from frying. I recommend replacing the the whole compressor. Good Luck.
There is a short. Shorts blow fuses. The motor may be bad - or need lubrication or a short on the wring leaving the fuse box to where ever it goes. Unplug the more and try a new fuse!
for fuse to keep blowing, there is a short in the eletrical system somewhere. check the a/c switch and the a/c clutch
either the fuse that was put has too much wattage or not enough
The fuel pump is shorting out and that is why the ecm fuse is blowing .Disconnect the the fuel pump and try it again,if the fuse blow's again then it is not the fuel pump.
There is a short somewhere.
The fuse is blowing because the circuit is overloaded, there is a short in the wiring, or the fuse is too small. Be sure you use exactly the size fuse that was installed at the factory. A larger fuse may not blow but it also may cause a fire.
Short in the wiring or the starter is defective.
Short some where.
You have a problem with the electrical circuit.
