Re: burned fuse at power relay Sign In
That fuse has nothing to do with the IAC. It powers the injectors, PCM, fuel pump relay and Mass Air flow sensor.


Shorts can be rela tough to find, especially if they are intermittent. The procedure is to basically disconnect and isolate each component until it stops blowing the fuse. If this is intermittent, you obviously can't unplug these sensors and drive around. What you may have to do is rig up an ammeter that you can put in series with each of the components individually to monitor while you drive if the draw becomes excessive. The fact that the 20amp hasn't blown indicates that it's only excessive draw and not a dead short. That makes it even harder.
