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.
Disconnect the electrical connection at the blower fan motor, put a new fuse back in and see if the truck starts and runs without blowing the fuse. If so replace the blower fan motor. If the fuse still blows, disconnect the ac clutch wire from the ac compressor and try again.
More than likely the a/c compressor is bad. The compressor clutch could be shorted also.
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)
it was the fuse. it is in the glove box it is maked (cluster) 10 amp fuse fixed it all.
Your ugly stupid.
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.
Compressor has seized.
either the fuse that was put has too much wattage or not enough
It is drawing too much current. If you aren't certified for AC repair, roll the windows down and drive to your favorite shop.
Defective blower motor? See if it is sgetting power Blown fuse?
I would lilke to know the answer to this as well. Having the same problem all of a sudden.
