How do you change the driver side window motor on a 1998 Lincoln Navigator?

This is not the easiest job you can tackle, but you CAN do it. But unless you're highly intuitive, or have done some mechanic work, it'll beat you. THE BEST WAY TO START is to buy a repair manual for your model car. I like the Chilton's version, but there are others. Haynes comes to mind. I bought a Chilton's through Amazon.com for my '89 Geo Metro. Under $15, and the best investment you'll make. I won't go further. I personally would not tackle it without a manual. Good luck (I have to do the same thing on both doors of my 2000 Camaro SS, and I'm dreading it.)
