I believe the lines or holes were the washer fluid sprays out may be clogged. What can use to clean them?

 

You can clean the holes the water come out of with a sewing needle or pin, just poke the holes, if that doesn't work, I would pull the hoses off of the nozzles with the hood open, and see if you can get fluid to come out of the lines, if it doesn't come out with the nozzles not on, then it's the nozzles, you can also replace them for about $10 a piece from the dealer, I have a set on each of my hoods. Most likely it's the nozzles that are plugged, try the pin/needle first. Also make sure your fluid is full

 

also you can dip the needles in vinegar and that should get rid of the clog for sure.
