There isn't one; it's an all one unit. When you fill the front one, the back one gets filled too.

That is another fault with the Optra 5, 2006, which I too have. There is only one place to fill up the wiper washer fluid, in the front, to the right next to the battery. The problem is in the rear hatch that lifts up; in the top left corner, you will find that the connecting tubing turns at a ninety degree angle and then kinks, cutting off the supply to the rear wiper jet. Even my dealer did nothing. I fixed it myself, cutting out the kink, getting a right angle piece of brass tubing from the Canadian Tire plumbing section and joining the two - you might also have to extend the tubing with a straight piece connector as well. When my rear wiper jet stopped working, it showed up in the inside of the left car seat upholstery, soaked with washer fluid, which I then had to have shampooed.

Hi there. The rear wiper's spray does not have its own compartment, it all comes from the compartment under the hood.
