The doors lock/unlock when I am on the drivers side, there wouldn't be two receivers would there,or could it just be a brocken wire behind it.

There should always be one IR receiver at the driver's door. Many cars have an IR receiver on the passenger door too but not all. In addition to these you have an RF receiver (a single one, the position depends on the car model). The RF connection allows you to open/close doors further away than the IR, it is not directional like IR, you can even be around the corner. As mentioned earlier, if your windows do not open/close with the key from the driver's side but they do on the opposite side, the IR receiver at the driver's door must be broken. Doors are still opened also from the driver's side but not with the IR function but the RF connection.
