Windshield wiper sprayers

I would start by checking fuses. If you've checked already, then the windshield washer pump has probably gone bad. The wiper motor and washer pump should be separate units. Typically the washer pump is located in the base of the washer fluid reservoir.

1. check your windshield washer fluid level.
2. make sure you can hear the fluid pump operating when you operate the switch.
3. If you can hear the pump working and you have fluid in the reservoir but still no spray,
   
4. check the washer fluid lines don't have holes and aren't clogged or pinched. check the sprayer nozzles make sure they are not clogged with debris.
5. if your washer still doesn't work your fluid pump is probably the problem.
   

If the pump works, something should be flowing thru the hose to the spray nozzles.
And if the pump works, everything electrical is working.
How do you know the pump works ?

washer pump needs replaced

Sometimes disconnecting the battery does more damage then you want it might have trip a fuse or relay check those if thats not it, maybe wiper motor or transmission went out.

your motor could be bad you could have a bad fuse or there is something in the line or there is something in the sprayer head. if you listen around the sprayer motor you should be able to here is it is working or not if it is working it is probably something in the line or sprayer head if it is not working than it is either a bad motor or it isn't getting power if the motor isn't working I would start with the fuses.

your rear wiper motor might be faulty,in the front i would check your fluid level-if it is full and you hear the pump running-check your washer lines to see if they are pinched-usually around where the hood closes

Check to see if the sprayer motor is working you would hear it making sounds like it wants to spray. If it is working then you need to check the hoses running to the sprayers on the windshield wipers and make sure that the hoses and the spray nozzle are not clogged with dirt or frozen.

This could be 2 things.

First of all, check for any debris blocking the sprayer holes.

Secondly, open the hood and make sure the hose running from the washer fluid tank is connected to the bottom of the sprayer.

it might be in the motor pump or line is clog can you work the hose
