In the rare event I have the actual regulator fail (not just the clips)... I buy a used OEM regulator, swap my motor onto it, install new aftermarket sliders and retainer clips onto it, and then do the zip tie mod that takes all the strain off that stupid little plastic tab that holds the cable in the slider. Haven't had a modified one fail on me. Yet anyway.

Most of the system is robust but a few key things sabotage the whole window lift.
