I have replaced the drivers door regulator on my 2005 twice. The first time I went aftermarket. When that lasted only a couple of years I went back to the Motorcraft version. The aftermarket was about $150 and the oem was IIRC $225. As someone else said, replacement takes about an hour.

The first time it failed I was in a store. I came out into the parking lot and the window had fallen down into the door. I had a pistol in the center console at the time. Nice.

The second time it failed I was driving down the road when a storm hit. One of the plastic pieces connected to the cable snapped. Once again the window was headed down into the door. I was able to drive home through the rain holding it up with one hand.

Now I don't trust the damn window to stay up and never lower it if I don't have to. Pain in the butt but like someone said it is paid for.
