Default Re: Help with fan circuit

Ok,

The AC is not charged right now, so I don't know if the fans would turn on based on AC pressure.

The secondary fan does turn on when the forked key that I got at Autozone for the OBDI connector is plugged in.

I found the wire from the terminal block to the fusible link was melted, and burned in two. After replacing it with a fuse, it instantly blew the fuse when I plugged in the "key" to the diagnostic port.

Hmm, the plot thickens.....

When I take a direct lead from the battery to the fan lead, the motor sounds like it is full of marbles, and the wire gets REALLY hot REALLY quickly. I'm sure the brushes are toast in it.

Anybody had luck with aftermarket fan motors?
