    Hey All~
    I've got a 1990 740 Wagon with very low pressure on the wiper fluid.

    What happened several months ago is that no fluid was coming out.
    Checked jets and they were plugged. Unfortunately broke one when
    cleaning. Replaced it and fluid now flowing just fine BUT there is
    very low pressure.
    These jets are adjusted all the way up and water just spurts barely
    onto the windshield. Checked the lines, the jets, even replaced the
    pump. Still no change.

    Oh and the back fluid is just fine!

    Any ideas? It's my wife's car and she's driving me crazy to fix it!

    Does the '90 have the same checkvalve/splitter between the two jets as the
    older 740s? I've had to replace that on mine before.

    When this problem initially happened that is the first thing we
    replaced!
    Went through everything again....and took the chance on that part and
    bought yet another new one~ voila! Guess the new one we got was
    faulty...sure caused me some headaches!
    Thanks!
