how can i fix my electric windows?

You will need to discover why the fuse is blowing - obviously because too much current is being drawn - but why is that happening?

Which window?
More than one window?
Going Up?
Going down?
Going either way?
What car make & model?

You may need to buy a big bag of fuses but probably better to inspect the mechanism and the drive motor and look for signs of damage.

When I last had electric window problems I called out a mobile car-locksmith.
