Windshield washer relay location?

I have no spray from my windshield washer. the fuse is good, the pump is good (i pulled it and checked it with a power supply), there is power at the pump but no spray will come out when either pulling the wiper handle or pressing the button on the end of the lever. There has to be a relay somewhere that is bad. anyone know where it is?

 

Yes i searched and was unable to find the answer.

I don't see a relay in the wiring diagram.

so is it the switch on the level then? it just seems weird that both could fail at the same time. well i never use the button just the lever so maybe the button has been bad for a while

I am not sure from your original post...is there power at the wiring harness that plugs into the pump or not? You said that the pump runs when you hook power up to it. Maybe the lines are plugged and the pump is indeed running?

Well first, when you pull the handle, fluid will not come out anyways. Have you checked to make sure there are no clogged lines and that the harness is plugged in on the washer bottle?

the pump runs when i powered it with a power supply and still shoots water, when plugged into the harness it won't run. both sides of the harness are +12V to ground, the fuse is good and there is power there too. I guess that switch in the lever must be bad.

Nevermind.

I have the same problem... did you had to change the lever finally?

no i haven't, its been too cold here to work on

My washers aren't working, either. The rears work fine but the fronts don't work at all. Are they on separate pumps? On my last car there was a sort of check valve in the lines to the washer nozzles that would fail eventually; I hope someone has a similar (easy) fix

I'm having the same issue. There are two plugs that can plug into the motor, but only 1 motor. Anyway each plug has two wires and I measured 12v from each wire. I ran the motor off of the battery and the fluid sprays fine any ideas?

any ideas?

Same, front nothing, rear just fine?? Just started today and I am on vacation too.

Can I get a follow up on this problem? I just bought my legacy yesterday and it won't pump any wiper fluid either.

My 97 Legacy just had the same problem: Front w/s washer pump doesn't work. Pump works. No power to pump. Info appreciated. If I figure out the answer, I will post.

If there is voltage at the pump when its unplugged, but the pump won't turn when plugged in, that tells me there is high resistance in the circuit. This could be a loose connection, defective switch or wires corroded internally. Wild guess is you used water in the reservoir in summer and its corroded the wires leading to the pump. Cut away the bad wire(s) and replace.

 

Much as I like to think I'm enviro-consious, I don't run straight water in my WW in summer. I usually dilute 50:50 to avoid the corrosion problems.

I solved my problem by discovering the button on the end of the knob.

Thanks Entrepit!

Neither my end spray button or the "spray and wipe" worked when it was 25 deg outside. Now at 50 deg, the end of stalk button works! Am I looking at tearing into the steering wheel ? Are the contacts accessible with spray contact cleaner?

On my 2004.

Both pumps are mounted to the front of the washer tank in the Engine compartment. My rear wasn't spraying, while the front was.

 

To troubleshoot. Apply power directly to the pump. This is the recommendation from the Subaru shop manual. The connectors are keyed and different for front and rear. You can't mistakenly reverse them or plug them back on wrong.

 

The pump closer to the fender is the rear one, the one closer to the engine is the front one. The pumps operate by applying Ground, and are hot with the key in Run or accessory. The power connector to the pumps have a latch to hold the connector on. Press this in while you pull up on the connector to remove.

 

The terminal closest to this latch is the ground. The one farthest from the latch is hot. I built a test harness with the following:

• red and black 18 AWG jumper wire. - scrap from a PC powersupply
  
• Inline fuse holder
  
• 2 - Crimp on 1/4 inch (pushon) spade terminals - 1 insulated
  
• 2 - Crimp on Forked connectors.
  
• Momentary contact switch.
  

 

I connected the wires to the battery with the forked terminals at the terminal bolts.

I put the fuse holder on the +12v side. I put the insulated spade terminal on the end of the hot wire and connected to the pump terminal farthest from the connector latch. I connected the jumper ground to the battery and installed the momentary contact switch on the ground. I connected it up and pressed the switch. It operated the front pump but not the rear one.

 

I removed the rear pump from the tank and tapped it on a hard surface. (read: butterfingers fumbled and it hit the driveway) It must have freed something up. I applied direct power again, it started working again.

I got mine fixed!

 

Is was poor contact from the wire connectors. Previous owner must have had a leaky battery, acid/ or fumes had got into the connector and corroded the contacts. Cut off the connectors and put spade connectors on the wires reconnected and all works well.

 

My wiper problem is fixed too. The wipers were stopping Mid windshield when turned off, you had to turn off when they were down.. Now the wipers return normally. A nice side bonus to my Work!

 

@ICT

Don't tear wheel yet. You probably have a bad contact at the pump. Colder temps can cause poor electrical connects to fail. Or you may have had frozen washer fluid in the lines..

Good luck.

So yesterday my wagon wouldn't wash the windshield the way I've been doing it for 15 years.

 

Post 17 fixed the problem. Never knew that button was there. After having a 98' and 00' Legacy GT wagons, I just figured the 05 worked the same way, pull the lever.

 

See you can teach an old dog new tricks.
