Windsheild Wiper Fluid will not squirt on windshield

faulty switch. I would replace that first thing.

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.

go to a service station with an air compressor and with the air turned down to about 20 lbs blow into the washer top small hole to force fluid thru the hoses,not a lot of pressure so you blow hoses off or rupture something

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

Either the pump is bad, or the nozzles are clogged.

If I remember correctly, pump is in the same bottle as front unit. Makes sense, otherwise you'd have two bottles!

Motor is right behind where arm connects to it. You need to remove inner panel.

check the outside first pull the fluid line where the fluid should be coming out have someone stand there if it comes out there the nozzle is plugged work a pin or needle inside of it to loosen it up if thats the case

I just fixed the wiper jets on my car this evening - you may have a similar problem of having hardened gunk (deposits) blocking the sprayer. Removing them is relatively easy: Open your hood and note that there is most likely a vibration-dampening cloth/fabric secured to the inside of the hood. You will need to remove the round discs that are holding this in place (most likely Christmas tree plugs - there are around 8 or so). Once removed, you will have access to the back of the sprayers. Some are held in with a nut, others are clipped in to place. You can remove the sprayers and try cleaning them or you can replace them with new ones (relatively cheap and guaranteed clog-free).

the little pump inside the washer fluid reservoir is bad, replace it
