Windshield sprayers not working

[TOBASH]

Searched but not getting any answers.

1981 BJ-44 from NZ/Japan with 24 volt ignition and 2b engine.

Windshield wiper fluid won't spray.

Wipers work fine. Just no spray.

1) Do lines have check valves that get clogged?

2) Where is the pump/motor for me to check continuity.

3) Are there any other things to check like relays, etc...?

Thanks in Advance.

Check the washer pump on the bottom of your washer reservoir. (I think yours should be similar to mine here):








See if it is running/humming when you switch the washers on and/or check whether juice is being supplied to the connector.

Another possibility is "gunge" in the lines that is blocking your spray nozzle holes. Algae can grow in your lines -especially if the water isn't treated properly and/or has been sitting (without use) for a long time.



PS. I'm not aware of any check valves - but one could be hiding in the white plastic "union" I see in my tubing-line near my brake booster.

undo the hose from the sprayer on the bonnet to see if water gets that far.

I have had this problem before and have had to replace the sprayer.. it was a clogged sprayer on the bonnet that was the problem.

Best,

P.S. if there are more posibilities, please post.

Avoid the drunk helpers

I am guessing that the problem is solved by now. But I can relate my experience with unclogging mine.

1979 FJ40, 350(soon to be 4BTA)

After a drunk guy tried to help me in the parking lot of the gas station by hitting the side of the fluid reservoir till it cracked and dumped most of its contents on the ground. Apparently believing that the knocking would free something up and make the Pump motor work better.

So after repairing the reservoir, I began tracing the line seeing where it was clogged. Turned out to be clogged in the hard line that runs through the windshield frame. After several hours of swearing, and feeding 18 gauge wire in and out of the line along with a large dose of WD-40, I removed what appeared to be a large chunk of silicone.

One of the previous owners had attempted to reseal the hard top, and had removed the spray nozzle and filled in the entire top of the window frame with silicone. How they managed to get some into the approximate middle of the line I will never know.

I found on mine that i was not getting any juice to the little electric motor that sends a surge of fluid onto my windshield.... I turned the wiper switch to the squirt position (about 3 oclock) Pushed and pulled the knob a few times, and freshend up the contacts that complete the circuit... Once this was done my lil spritzer moter was hummin like no other Give it a shot

Thanks all. Let me tell you what my problem actually was.

It was not a clog.

It was not sludge.

It was not electrical.

I first cleaned all the electrical leads. No help there.

I then checked for electrical continuity, and I got 24 Volts without a problem.

All the lines were free of debris as determined by being able to push air through all lines fairly easily.

So I decided the pump was shot and it was time to look at it.

I carefully removed the reservoir/pump assembly. It hits the brake master and I hoped it would not crack. Thank heavens it slipped out without breaking.

My sphincter puckered and my testes retracted as I gingerly tried to remove the rusted 26 year old screws holding the impeller to the reservoir. I was afraid they would rip plastic or twist their heads off. I had pre-sprayed with PB Blaster.

Screws came out and I soon had the impeller in my hand. The prop on the impeller would not turn. I sprayed with PB Blaster and turned by hand and freed it up. Still felt tight, but I decided to hit it with electricity.

Impeller whizzed like a champ!!!

I coated the screw tips with anti-seize on reassembly. Everything fit great and water tight.

I refilled with Rain-X windshield wiper fluid and all is well. I just need a shirt pin to slightly re-align the sprayers and slightly unclog the non-driver's side sprayer.

Success!!! I feel like a king, despite the fact that this was probably the simplest 1 job anyone could do. ( I managed to fight the alcoholics away Farmboy, just barely.)

Thanks one and all. Lost Marbles, the pictures were especially helpful and were much appreciated!

Best,

P.S. I am used to Saabs. All things Saab are complex and convoluted. This 1981 BJ-44 seems straightforward and much easier to work on. Woo Hoo!

X's 2 on feeling like a king after fixing the windshield sprayers.
I've poked and proded around trying to get that thing going for a while too, with no luck. But after reading this thread they are now spraying like champs.

Thanks Guys.
