1st check for a blown fuse. if the fuse is good it might be washer pump has stopped working. A replacement is cheap and an easy repair. the pump is located on the side of the washer bottle.
check hoses that run from the washer pump to windshield and also the ones that lead to the reservoir tank. Something is broken causing there to be no spray.
{: ) The rear washer pump is attached to the washer fluid reservoir. Below the left headlamp assembly. Ignition on, engine off. Switch ON the rear washer control. If you can hear the rear washer motor works, check for clogged hoses and tubes. If it's not clogged, your motor could only be running but not pumping.
If you cant hear the washer motor at work, its probably faulty.
To rule out if its a control switching issue, get a test light to check for voltage at the washer connector if you could only access it. Its better to check on that end. If you cant access it, at least probe the rear washer fuse at the underhood fuseblock. The test lamp should light everytime you switch on the rear washer switch.
it is a hose problem, there is only one pump for both nozzles. there is probably just a bit of debris caught in the nozzle. disconnect the line under the hood, and blow compressed air back (reverse) through the system. may take a couple of tries but should work. good luck!
Check the washer pump. It is located under the air cleaner assembly. There will be a connector with tow terminals. there should be power on the red wire anytime the washer button is pressed. There should be ground on the black wire at all times. If there is no power than check the washer fluid fuse and relay in the underhood fuse block. If there is power than the pump is probably bad.
