Window motor and spring. Is it safe to? help

The motors have a worm gear and ring gear setup inside of them.
Often when the worm gear strips the motor will run and then make a ratcheting noise and the window will stop moving.
The only way to fix it is to replace the motor.
If it has the coil spring on the regulator and the service procedure calls for removal of the regulator, yes that thing certainly can take your fingers off.
I almost broke my hand on one a few years ago working on a GMC Suburban endgate. I thought I had shattered some very important bones in my hand but it turns out that milk does the body good.
(it still hurt... bad)

At any rate, there are ways to remove the spring once the regulator is out of the car. They make a special tool for it, but I can never find it so I have a method that works with a couple pairs of vice grips.
Some cars let you change the motor right in the door.
Some require special rivets for reassembly.

Am I right in thinking that the motor and the regulator are one unit. The motor part has 4 torx bolts and the whole unit comes out with 3 bolts. With the noise it is making I assume I have to take the whole thing out and it is the worm gear or the gear on the back side that makes contact with the half moon large, flat, metal piece that is spring loaded. I really need someone who has taken this apart on this specific car to tell me what will happen if I remove the 3 bolts and pull the whole unit off what will happen. Does the window have to be in the up position so the tension on the mechanism doesn't slam the whole thing once the tension is off the spring? I think it will be the same on a 96 or 97 STS, all other years might not be the same. I have changed the type with the cable before but I have not had to deal with this dam coil spring.
