Not much info to go on but here goes. If the wipper doesn't work as well it's more than likley the fuse. If the wipper works then it's either the pump or the wiring. Easiest to check is the pump. you can get at it from under the front wheel arch ( have to loosen the plastic under cover) mine was the front pump not working, I removed it and the rear pump and wired the rear lead into the front pump to prove it was the pump faulty. Believe it or not giving the pump a sharp tap on the floor got it working again please note the wiring plugs are not the same size so to test it this way you'll have to use a bit of wire from the rear wiring plug to the front pump. It's about a 30 min job. good luck
need windshield washer motor
There are Two separate motors for your window washer one for the front one for the rear, they are both in the window screen washer bottle at the bottom.
Any brand washer fluid will work.
The most common reason for any window washer malfunctioning is the washer fluid is low. Rear window washers can be more complex than front ones, so if the washer fluid is not the problem, it needs to be looked at by a mechanic.
cuz your stupid
It is attached to the bottom of the washer reservoir. It shold be at the bottom ro near the bottom of the window wasehr fluid container. It is relatively small - there is a wire coming out of it. Follow the hose(s) coming out of the container - or work backwards form the window sprayer and follow the little hose.

Relaced the washer motor and it still does not work? Check the fuse, if it is good then you have a bad connection somewhere.
Please be more specific with your problem. Is the sprayhead stopped up with sediment? Does the wiper not work? What? There is no washer pump in the rear window. It is nothing more than a spray head that is connected by tubing to the same underhood washer pump that supplies the front windshield sprayers.
does the front work? if the front DOES work, it may just be the hose to the back has a leak/hole.
Both washers work from the same tank under the hood.
R/window wiper and washer are two separate things. Washer is simply a pump that squirts fluid onto window. First, have you checked the washer fluid level? How about the fuse? When you push the washer button can you hear the pump running? If not, possible bad pump, fuse or button. If so, maybe the pump is clogged or fluid delivery tube is plugged or disconnected. Hope that helps.
