Windshield fluid pump system - check valve failed - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

zeroxg35 · 07-24-2018, 12:29 AM

Hello,

I own a 2014 FRS - and more recently I started having issues with my driver side windshield nozzle. It was not spraying properly - and had a very weak trickle. After troubleshooting, I identified the culprit as the 3 way check valve.

Has anyone else run into this issue?

Symptoms:
- spray was weak from one side - but seemed stronger than usual on the other.
- motor pump is more audible - still in working condition
- no change in spray pattern was seen when swapping the nozzles from left to right.

Part Number: SU00302699 (*had difficulty finding as of June 2024)
Alternative Toyota Part Number: 85321-28020 (Valve, washer)

Part #29 in this diagram

Nice diagnosis. Hope you weren't stranded somewhere.

Woh, my driver side nozzle has been weak as of late. Might be worth a shot on checking it out.

Oh, that just happens when you get older -

Just spread your feet further apart, so as you don't pee on your shoes.

Stick a pin down the hole to clean your pipes

Keep us posted if this resolves a progressive issue? Thankfully the part from the dealership was only ~$3.50

Oh, yes, I get that. Once every 6 months the urologist runs a scope up my pee pee tail into my bladder and up to my one remaining kidney, to make sure the cancer has not come back.

Yep, THAT is a weird feeling -
