    I'm having a bit of trouble with my wiper fluid sprayers. The reservoir is full and I hear the motor going when I pull the wiper stalk, but no fluid through the nozzles. I read this previous thread and covered my nozzles while my gf pulled the wiper stalk.

    Windscreen/windshield squirter reboot problem

    Wiper motor whirred, but I couldn't feel any pressure at the nozzles. The fluid in the reservoir looks like normal wiper fluid (atomic blue in color and seems clear. Per the older thread there was some talk of disconnecting the lines from the reservoir to the nozzles. Any idea how to get to those? Or should I just wait for my next service?

    I was running straight water in my reservoir which I believe caused algae to grow and clog the lines. Took all the hoses out that were visible, they were all clear so the clog was down lower where I couldn't access the tank nor did I want to rip into it. Before diving into the teardown task the line broke free. My guess the enviro that was keeping the clog alive down there wasn't optimum. I then poured a mix of white vinegar / water for which I've been clog free ever since. Still running the vinegar / water mix.

    Are you running the std. antifreeze/windshield washer liquid in there? That should not allow things to grow in your lines, and your issue may be a different flavor of a clog.

    I don't know how to quote a thread name - but look at "Weak Windshield Washer" - good info there. My washer pump was clogged with bacteria/fungus, the SC cleaned it out, and then sterilized it with alcohol before adding new washer fluid. They said it was gunked up because of lack of use - (it only had 1000 miles after three years).

    I just bought the car last week, but it does look like a thick atomic blue fluid, which makes me thick antifreeze + washer fluid.

    Any paint concerns with running vinegar through the system?

    I use distilled white vinegar, they sell it at costco, and dilute it with water. It won't harm your paint. Some people use it to remove water spots on their car. They say it will make over time your car look dull and that's because it does break down the wax protectant coating over time but that's remedied by reapplying the wax. Should be doing that anyways just to protect the car. I honestly haven't yet.

    I've been running my hardtop for sometime and using the vinegar mix, and where the water runs across the top from the windshield I can't see any difference in the paint. Still people say the car looks like new even without the re-waxing so in my observation and other's its fine to use. If you're really concerned you can pick up a ph meter and dilute the water/vinegar mix until its just acidic enough so that bacteria and algae cannot survive.

    Some say that the (actually any) antifreeze additive which is in your typical windshield washer fluid is not good on the wax either.

    How much vinegar did you add to the system?

    With the help of a chopstick for stirring, a turkey baster and empty boba tea cup, I found the problem. Algae... sucked most of it out, ran some vinegar through the system, filled up again with wiper fluid. I will continue to monitor the system.

    I too suffered the scourge of tank crud -- ironically after having Telsa service supposedly clean the system last service.

    I discovered this morning, after an unfortunate bird pooping incident that the washer was totally plugged. It was a smeary mess.

    I ended up doing the following:
    Hand pumped most of the tank content out. Shop vaccumed the remainder interior.
    Equal parts near boiling water and vinegar. Wait a few minutes. Agitate with hand pump for a few minutes. Wait a few more minutes. Pump out tank, shop vac. Interior of the tank is now spotless.
    Disconnected the hose at the check valve just south of the sprayer. Attached feed hose to extension and fed into bucket. Refilled tank with equal parts near very hot water and vinegar. Checked flow from washer pump, flow ok. Drained tank with washer pump. Purged some line crud.
    Pulled the check valve. Soaked it in near boiling water and vinegar for several minutes. Attached it to the the hand pump and cycled a lot of fluid through it. It was extremely clogged, clear now.
    Reinstalled the check valve, hooked the hand pump to that. Cycled a bunch of very hot water and vinegar through that. Slightly clogged now clear.

    Washer is now working better than at any time since I've owned the car. Almost too well -- seems half the spray is hitting the roof.

    Swapped to orange (methanol'ed) washer fluid.

    slightly off topic:
    is there a way to re-aim the nozzle? Mine just sprays completely OVER the car

    You stick pin in the nozzle hole (its a ball socket) and direct it where you want. Usually high on the windshield so it hits the middle while driving.
