My passenger side front window will go down but not up. I've replaced the d.s. master switch & p.s. regulator. I've checked for broken wires, but think that if it was a wire issue, the window wouldn't go down, so I've pretty much ruled that out. If it was a fuse, I wouldn't have power to put it down, so that's ruled out too. Anyone else have any ideas? Has anyone else had this issue?
