i have done quite a few of these ,bit of a pain.firstly you need to remove the interior door panel,various srews and clips hold this on.be gentle they brake easy,rip off the black plastic allowing you to look into the inside off the door.you will see a black box(cover)at the lock mechanism.anti theft device.you need to remove this.on the door check ,below the part that locks onto the b post there are two pop rivets drill these out then cut the black sealer away around the box,pull this free.you should now see the back of the lock.using a screw driver twist the retaining rings anti clock wise on the back of the lock from each other.these are solid.once free jiggle the lock,pop the small connecting rod out of the end of the lock.now reverse the above process.make sure the black cover is secured as this affects how your window goes up and down
