Thanks, but the LS arrangement is different. It doesn't have those parts to break. Instead, there are clips at the ends of the cables that break. After that, the regulator itself is destroyed by the cables wrapping around the drum incorrectly.
Well, the regulator designs is more or less based on the same principle, that is: Cable operated by means of an electric motor winding up the cable on one side and releasing it on the other side into a spool inside the gear case. This will make to cable, that is attached to a slider in the regulator assembly to move up or down. Now the glass is bolted to that regulator assy. What I mentioned was that inside the motor gear assy, there are 3 plastic balls that were destroyed=churned, smashed and grinded into little pieces, thus rendering them inoperative to act as a locking mechanism inside the gear.. is something like a clutch but uses those 3 balls. I wish I could post a few photos to show you what I mean...
Now, also the regulator, has 2 "cheap" plastic grooved rollers to guide the regulator cable up & down. But tose rollers are not sold as spare parts, thus you are forced to buy an entire new regulator just for that broken little roller. Same thing goes to the external plastic clips that are mentioned...
Another cause. is the glass runners, that are adjusted, but if too tight, will impose extra effort to the motor, and thus, the cables, causing it to snap the cables, brake the rollers or the plastic clips, etc.. or ultimatedly, smoke the motor.!
Once I learn how to post photos, I will, thus an illustration is worth more than a 1000 words.
Hope this will help you to look further into other possibilities.
