VS power window problem

[scottmc1234]

I got a 1997 vs berlina.
The drivers power window won't go up but it will go down. It did initially work sometimes when I hit a hard bump.
When I got my subwoofer installed, the installer said it was broken.
How do I get to where the cable could possibly be broken?
thanks

I'd say it's your switch try swapping that first.
