My passenger side door latch stopped working. I removed the panel (broke the switch but can replace that) and reattached the cable to the interior door handle and loced it into place. But it seems the cable has become unattached to the latch itself or has broken on that end. When using the rear door handle I can hear the end of the cable moving around near the door latch. I cannot reach far enough back with my hand to reaatch it to the latch. How is this done?
