For about a year our 2003 Suburban had driver window issues. when pressing the button to roll up the window it would stop 1/2 way then you would have to wait about 30 seconds press he button again for the window to roll up.
Now it has completely stopped working. The other windows work fine.

Is it just the motor or do you have to replace the whole assembly?

 

If it is the regulator, you replace the whole assembly. Cost from $45-$100+ for the part. Take a look at this How To Remove Door Panels On A 2002 Chevy Suburban - 2000 to 2007 Model Years to see how to remove door panels on your suburban to decide if you want to do it your self. There are tutorials online for actual replacement of the the regulator. But it could just be the switch, or a wiring problem, so I would troubleshoot that first.

 

Probably just the motor. Since you have to pull the panel, it is easy to check.
