2002 Mazda B4000 - Blown #2 Fuse

[pnryan79]

Having an electrical problem with my '02 Mazda B4000. I am blowing the 10A #2 fuse (blower motor). Every time I replace and turn on ignition, the fuse blows almost instantaneously. Has anyone expreienced this problem or can at least give me a starting point for dignostics? Winter's coming and would appreciate a little heat in my cab!

I feel your pain. Mine does the same thing. Mine doesn't pop instantaneously, with a 15 amp fuse it takes about 15 minutes blower on full blast to pop. The way the most recent fuse popped for me was putting it in reverse causing the reverse lights to come on and therefore it drew a bigger load and popped it. I am looking for help aswell, I just bought my truck so I am a little mad it is happening. Thanks to anyone who can help us out.
