My power window fuse keeps blowing whenever my window either gets all the way to the top or all the way to the bottom. My window regulator broke, so I bought and replaced the entire unit (with motor) from Autozone. After installing the new unit, I find this fuse blowing problem. The original window problem was a broken nylon pulley that the cable passed through. I had to replace the entire regulator (which included a motor). The original Lincoln motor will not fit the Autozone regulator. I'm not sure if the problem is with a bad Autozone motor (that's part of the new regulator assembly) or did I pinch a wire causing a short? I'm not sure how to search for a short. I visually double checked all my harnesses inside the door and could not locate anything that might look like a pinched wire that's grounding out.

You need a multi-meter.

Pull your fuse and place the meter on DC-amps. Then place one lead in each contact where the fuse inserts in the fuse box.

Then have someone activate the window switch all the way up and down. This will give you the exact reading of the amperage being pulled by the circuit.
And if there's any kind of voltage without activating the switch, then there's a short in the wiring somewhere.

Next you put the red lead on the power wire of the switch and the other to ground. If there's voltage or the light comes on, you have a short in the wire.

You'll have to trace it through the wires that pass through the door and go to the fuse box.
