Hey all, this is for the new (to me) 2004 Impala SS....

Driver's window has never worked, so I opened up the door panel and all that jazz.... regulator assembly is broken. The motor itself seems to work fine, it still seems to spin smoothly and properly.

For ordering new parts, should I order a kit that includes the motor, or just the other regulator hardware? Difference of about $70, from what I've seen. If the motors themselves are not known to fail, I'd just as soon keep using it. If, on the other hand, they do tend to burn out... I'll just replace the motor as well. Thoughts, guys?
