How do you replace a power window motor-regulator on the front driver's side on a 94 Camry?

Remove the interior door. Here is a web site with a good description on the steps you will need. http://autorepair.about.com/od/otherodddiyjobs/l/aa092504a.htm After the interior door is removed it is pretty straight forward, just remove the nuts that attach the regulator to the door frame and attach the new one. It is helpful to have a second person to hold the window up while you are working.
