The cable looks to be part of the regulator itself, so once you have the entire assembly out in your hands you should see a few bolts that hold the motor the mounting plate. Just remove these and pull the motor straight out trying not the disturb the gear in the regulator. Then just swap in a new reg. and give it a go.
I've never had an 04+ in front of me so I'm just going off of memory and pics I've found so not 100% sure how or if the motor can be separated, but someone built it so it has to come off somehow.
