My driver side wiper fluid line is severed from the thing it connects to under the hood. does anyone know if i can replace the thing it connects to or is it the whole system?

 

Not sure if your hose is just broken off or if your fitting is broken. I have purchased some hose from the auto parts store to replace the washer hose when it's busted. If that is the case with yours, cut a piece of the hose and take it to your local stores as a sample. They should be able to match the size and get you fixed up again.
