Faulty front screen washers - 10 reg

[Mac012]

We have had the car for 7 years and replaced the front drivers side washer jet valve in September 2020 and it appears to have gone again.  Is this a known fault for IQ's at approx. £70.00 a pop?

[Touring_Dave]

Do you mean something like this for £4.99?

What are you using for screenwash? Pre-mixed, concentrate diluted, washing up liquid diluted ......? If mixing your own solution, do you live in a hard water area?

[Mac012]

Yes to hard water, could put a descaler through the system!

[FROSTYBALLS]

Probably be better off using pre-mixed screenwash in the summer, and concentrate with or without filtered water, depending on what % you need, in the winter.

Is the pump working ? There is a one way valve these block when you use cheap screenwash - no issues in 12+ years using Autoglym screenwash - The water around here is so hard it comes out of the tap wanting a fight

one way valve 85321-28020

I second the one way valve, I sell ten times more one way valves than washer jets

Just had to replace my check valve. It only cost me a fiver. You can check if this is your root cause by switching the pipe connections around where they come out of the valve assembly. If the blocked jet has now changed sides, it's your check valve.

I realise this is an old topic but just had the same problem, diagnosed as the valve 85321 28020 and 

stupidly just ordered the first one I found (ebay), fitted and tried it, all ok, 5 days later failure, not worth sending

back so have ordered another from a different supplier, hopefully will resolve it.

kind regards

Well it seems that it hasn't, I fitted a new pump in Jan this year and now a dribble out of the passenger side and nothing out of the drivers side, I pulled off the in feed to the valve and water is coming out and I can hear the pump, so I stripped out the jets both sides and squirted silicon spray down them, it came out as a strong "mist" so they are I think cleaned, I then tried doing the same to the one way valve and spray came out of both exits so I put it all back together and nothing. So I'll order another valve 85321-28020

I am using pre-mixed screen wash

I've tried clicking on partsking, lindop toyota but the link doesn't seem to work🙄

Just done that, I still can't get my head round the fact that I can squirt silicon spray through the valve but it still doesn't work !!

thanks and kind regards

Just got an original Toyota part, works perfectly, as a tip to anyone else needing this valve, don't buy a cheap one off the well known auction site,

stay above £15 ie. Toyotaparts and you'll be ok.

kind regards
