Default Blower Fan Prob

Blower fan DOA. Check all usual fuses.... fuse on drivers side engine well, fuse panel fusable linc behind distributor. I pulled fan and bench tested placing dc power direct and still nothing. Don't want to get new fan if I'm missing something. Maybe a ground somewhere?

You bench tested the fan and it didn't work? But think there may be another problem?

If it won't bench test, it's gone. Any auto parts.

Open it up. You got nothing to loose if it's not working now. Probably the brushes are worn out or not making contact for some reason.

I pulled relay and check out purple wire. Toast! I jumped and crimped another terminal temporarily until I get a new plug. I picked up a used fan and installed. All back to working. But what caused wire to melt plastic plug to the point of meltdown? See pic.

Bad/corroded connection = resistor= heat.
