on each of my nozzles I have one side partial clogged, spray barely makes it to the glass. I have tried cleaning it with a very thin strand of wire, didn't help and it has worked on other nozzles/cars. I have been told trying to remove and clean them won't really work that it is better to replace them. any tips on removing and replacing them.. access from under the hood doesn't seem like the way to do it. thanks as always
