ABS light could mean a number of things.. ABS hydraulic module, sensors, or both for starts. But my question would be do you really need to fix it. MANY of us have never fixed our ABS.. some have even pulled the fuse for it. IMHO, you can brake faster with more control without it.

Take your VX to an autozone and have them get the codes. This will give you the information to diagnose the check engine light and perhaps the abs.
Doesnt cost much to do.

The fix for the windows (the most viable one) is listed by rowhard.
