Aloha guys.

As the title states, I need some info and input on windshield washer.

While ago, my washer was working fine. As a matter fact, it was little too powerful as the washer fluid went over the windshield and sometimes will spray the car behind me.

Now, that same washer doesn't have any power. Fluid comes out, but that's barely. It will spray only the very bottom of the windshield.

Is my pump going and need replacement or should I look for something else? I replaced the washer while back. I can't remember when so must be more than few years back.

raining season is upon me, and I need the washer to clean my window................

Hi Toshi, first try blowing backwards through the nozzles and lines with compressed air, in case there is debris clogging up the works.

Then use compressed air in the line going to the spray nozzles to test if the nozzles are clogged? If you have fluid in the lines, you can also see if the spray pattern is still good or if the nozzles are clogged. If they spray properly, you can rule out clogged nozzles.

Be sure you still have the filter in the pickup tube in the reservoir, and clean out the reservoir, if it is suspect.

That blue windshield washer fluid will dry and crystallize in the pump. in the nozzles. As Mark said pull the output line off the pump and blow air through it to see if it's the nozzles are clogged. I find on the 86 washers which doesn't get used much that the pump will crystallized the fluid and stop turning. Those blue fluids if not used all the time will harden.

Use a fine piece of wire.
Like something from a tag of some sort.
Or rip a wire out off a steel cleaning brush.
Poke it into the nozzle to clear it.
Remove the hose's from the nozzles and use the washer pump to make sure you are getting fluid up to the nozzles.
Also check that the hoses themselves have not split at where they get pushed on.
Large line (1/4") can suck air and the 3/16" line can leak.
No need for compressed air.

You might be able to soak the nozzles and lines in hot soapy water too.
Lines can also be replaced.

A point of interest on the nozzles however.
They were/are manufactured by dlhBowles, a US nozzle design company known for its "Fluidics Technology".
Bowles provides most washer nozzles for high end windshield, headlight and related applications.
Visited them in MD on a project (to eliminate aerosol cans...) a few years ago. Great people.
MAP - you are going to love this!
They design nozzles specific for each fluid/application to create an oscillating spray as the pressure fronts build and collapse (kind of a natural harmonic) in their proprietary static nozzles.

I purchased a set of aftermarket nozzles made off shore but am reluctant to use them. I will be cleaning out the old ones instead as per this thread.

Just use the wire and keep it K.I.S.S.
Keep it simple stupid.

Thanks for all the info guys. I never used that green or blue stuff, but I'll try cleaning them out first.

As I always say, I hate getting old. Never thought about cleaning the washer nozzle. I need to go back to basic, and try the simplest/cheapest thing first.............
