    I charged the AC and it blew cold, but the blower motor got hot really fast and the fan continued to blow after the ignition was turned of (turned it off with fan control on the dash). So I replace the blower motor and the relay under the hood and when I turn it on it imediately blows the fuse. Could there be a short in the cluster or what should I check?

    Shot in the dark here as I am not an A/C tech, but did you overcharge the system? I'm not sure how to tell when it's full, but I know overcharging it can be a bad thing.
