Window will not roll up on my 1996 Toyota 4Runner?

If the window in your 1996 Toyota 4Runner won't roll up, it could be due to a faulty window regulator, a blown fuse, or a problem with the power window switch. Start by checking the fuse related to the power Windows in the fuse box. If the fuse is fine, inspect the window switch for any damage or wear. If those components are functioning properly, the issue may lie in the window regulator mechanism itself, which may need to be repaired or replaced.
