[79BIG10]

I've been working on the Blazer and ran into a big issue. The rear window lock does not fit the keys I have for it. The rear window won't roll up so I know I have to fix that but even with by passing the window switch at the dash it still won't roll up. If I press down you can hear the motor engage and power. I'm getting power to the switch itself at the dash. I'm guessing I'm got a bad short somewhere between the switch and the window itself. But how do I change the lock in back out?
