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!
