I just replaced my regulator, motor, wiper motor, license plate bezel, and license plate lamps this past weekend. It's not hard to do the regulator.
Lower the window a few inches
Disconnect rear defogger on the side through the small access hole and connections on regulator/motor
Unbolt the window (3 per side) Window will not fall out, it's hard to get that thing out and back in again.
Unbolt the regulator and slide it out.
