Replace window regulator motor or not?

[JamesBound]

The motor might be ok. Try looking what caused the issue.

Disclaimer: I'm not a wrench, a Boxster owning friend replaced the regulator when I had a scratching noise. We didn't do anything about the motor as it was working fine and that solved the problem. Motor still works perfectly and the noise is gone.

Save the motor. They last a lot longer than the regulators. I have replaced about a half dozen regulators and never had to replace a motor.
