The windshield washers are aimed too low and they hit the wiper arms instead of the windshield. This means the windshield is dry during the first pass of the wiper blade and only spreads the liquid on the return (downward) pass. This is not very effective use of the liquid.

First make sure you have water in washer reservoir, with ignition on reds (not started) then get someone to operate washer while bonnet is closed otherwise the wipers (may come on) may damage your bonnet (would also be a good idea to throw some water on your screen before commencing), listen for a buzzing noise, if you can hear that noise than your washer motor is ok, if not - if fitted with fuse check it and if fuse is ok than your motor needs attention. If motor is ok than while someone is operating the washer motor look under the car to see if there is any water leaking, if there is water leaking than the hose going from your washer bottle to your washer nozzles has come off somewhere, visually check this hose, usually small diameter and clear in colour, reconnect or replace it. If there is no water leak and you have full water and motor is working, than your nozzle, usually located on the bonnet or wiper arms are blocked, this mainly happens after polishing the vehicle. There are 2 main ways of cleaning these nozzles, easiest way is to get a fine pin and poke it several times, this will clean it 85% of the time, if it does not work than you need to find the hose that connects to it and pull apart at a join, closer to the nozzle the better, and give it short burst of compressed air, have to be careful not to pop the hose out at the nozzle as some of them are located in really awkard points, hope this helps.

on the wiper arm, there is a cap. remove cap and there is a nut underneath, remove nut spray wd40 oil on the threads that are exposed, then slowly wiggle arm and pull simultaneously to remove.
SOURCE: windshield washer not working. Have filled it several times.
Check the hose from the container to the wipers and see if it came disconnected from either place and check for a broken or cracked hose.

The 2011 Camry has the nozzles mounted under the hood and the actual holes for the jets are not visible. Very different than on my 1998 Camry where the jets were on top of the hood and could be adjusted with a needle. The bracket mounted under the hood is very ridgid and seems to be not bendable. This weekend I will see if the nozzles have been installed up-side dowm=n.
