Even before all that....is there washer fluid in the reservoir?>If you can provide more details that would be helpful. Items to check and note: Neither side sprays? Does the pump function? Have the supply tubing become detached from the main tubing split connector? Is the main tubing from the pump still attached at both ends? Are the spray nozzles clogged? If the pump doesn't work check the fuse in the fuse panel (owner's manual shows location).
My rear washer fluid works but the front does not. So the fuse is ok? Are there separate motors for the front and back sprayers?.If the rear washer works, then the fuse is OK, there is fluid in the reservoir, and the fluid is not frozen. If the rear washer does not work then consider one of these things as being the source of your problem,
Next step, have someone operate the washer control while you listen for the sound of the motor ( place your ear very close to the reservoir bottle).
Look for pools of washer fluid on the ground underneath your RAV4.
It could be a clogged nozzle or bad connector splitter. Disconnect the tubing and see if any fluid comes out the other end when you use the washer.My rear washer fluid works but the front does not. So the fuse is ok? Are there separate motors for the front and back sprayers?.
