Is there any replacement for the crappy sprayer on the

How old are they? They might just be gummed up. Try taking them off and run a wire through the nozzles. If that doesn't work, buy new ones.

 

Dump a gallon of white vinegar in the reservoir tank, they'll clear out on their own. Needles will damage the spray nozzle pattern.

 

vinegar is the acid. so it may cause a corrosion of windshield frame is will not be washed out well after all is clean. So know that windshield frame is a weak point (yep, rust) of FLD

 

Go to Freightliner parts for replacement parts. I had to replace mine about six months ago.

 

Blow them out with air. If you don't have an air nozzle, just pick up a used valve stem off the ground in a Wally-World Auto shop (they're scattered all over the parking lot outside the doors) and use it for a sprayer. Spray air in it backwards, it'll clear out all the debris- good for another year.

 

You could take them off and soak them in vinegar if you're worried about it. If these are the nozzles I remember, they don't have a lot of holes, just 2-3 big ones, running a strand of wire, needle, toothpick in there isn't going to hurt them. If it's an actual mist sprayer, like a car, Bender's right. The last Freightliner I drove was a '98, they might have changed..

 

New nozzles don't make a difference. They are crap right off the bat.
