I did this on my 2000 sedan. It isnt that hard at all...

The worst part was getting the regulator off of the glass and wrigling it out of the door. Pay particular attention to the orientation of the regulator as you re-install... that can be a little tricky and if you do it wrong, nothing will line up and you will have to wrigle it out again.

The whole job took me about an hour and a half - including a trip to the dealer to buy the regulator.

Hope this helps!
