The drivers side washers are barely working on my car. If you put your fingers over the passenger side ones more water comes out on the drivers side but still pretty weak. How easy is it to remove the nozzles? - there doesn't seem much to get hold of from the outside. If I can remove them & soak them in vinegar/ viakal it will clear any blockage, failing that an airline ought to. Don't tell me its a bumper off job!
