i replaced the 2 nozzles earlier this year... it took me a total of 10mins.
Lexus wanted something like £160 for the privilege.  i did for £30. 

I think that the nozzles are clear - purely on the evidence of swapping feeds between the nozzles, i.e. the poor performance is caused by the reduced flow from the  backwards pointing outlet from the tee piece.     I may replace them just for completeness but I am going to fit a simple tee in place of the Lexus item.

I'm not sure what you mean by simple tee, but if it's just a splitter valve without any mechanism to prevent washer fluid returning to the tank... Then it's going to take a moment for water to come out of jets.

Hi Matt88

Just being lazy: yep, just a simple tee similar to this:

 

 

 

I will add a non-return valve in the feed tube.

Had the problem where passenger side jet pressure was very low. Found the valve without pulling bonnet cover off and tested by swapping the pipes. Sure enough the valve was to blame.

After much thought, I decided to go with the OEM Toyota part from dealer and the cost if anyone is interested was £22.20.

Very easy to replace and it made me feel good. 

This thread was very helpful, Thank you ...

Glad it sorted you out. My part was just under £15 when I purchased when I first made this post.

Now £22.20. That’s inflation for you!
