That is why I questioned about the way you wired the connector.

Thanks. Turned out to be the blower motor fuse, it had burned out.

I didn't wire a connector, it just stopped working all of a sudden. So I checked fuse and it was blown and keeps blowing fuse as soon as I even touch it to put the fuse in.

Check the connector for the correct wires to the resistor.

Okay, sounds like you have a short in the harness.

If this is the resister block at the blower motor the wires I have at the plug are (red, black, and tan with white stripe).

Another question would be is, would the Air Door Actuator have any power without the heater being on or blowing the fuse? Since I have all of the other heater units disconnected and it still blows the fuse.

The power to the actuator comes from the control head. Disconnect that as that is part of the fuse control.

Okay, I have the control head out, the control module out, the blower motor out and the heated seat /overdrive/rear window defog out and still blows fuse and you say its a wiring between control head and control module. Is that correct?

No, that is the blower resistor.

The control head is the control assembly on the dash board.

Okay, so the power comes from the control head. Hence why you said it will be between the control head and the blower motor.

If the fuse does not fail after you disconnect the control head, yes.

Okay, you have a wire harness issue somewhere in the harness.

It will be a time-consuming job to uncover the harness and look for bad wires.

I have unraveled all the tape, I see nothing that indicates a short or bad wire, not even sure how the fuse box comes off. Can I not just run power from a empty fuse? (Already frustrated)

Yes, you can do an overlay but you need to cut out the bad wire so it has no power and then run new wires to all the components it powers.

I posted the procedure and a couple of pictures.

(1)Disconnect and isolate the battery negative cable.

(2)Remove the fuse access panel by unsnapping it from the right cowl side trim panel.
