1997 Chevy Lumina Power Window Driver's Side

There's nothing wrong with your motor/regulator. Your switch either has a loose/corroded contact, or the wiring in the circuit that controls the "up" movement is loose/broken.

Replacing parts with the hope of solving the problem hardly ever works and only cost you money that could've been spent on a mechanic.

The proper way to diagnose this problem is with a test light. Use it to probe the switch as you depress it. If there's no voltage present at the terminals when you hold the switch in a certain position, then you trace that wire backwards until you find the break in the wire or a loose/corroded connection.
