I had to have my front heater blower replaced, and I had my VW mechanic
replace the heater coil, windshield washer motor and windshield washer
pump at the same time.  Yes, I can wash my windshield now.  However, it
takes about three seconds for the fluid to get to the jets.  Once I stop
the washing process, all the fluid in the line returns to the reservoir.
Is this suppose to happen?  Is there a check valve that can be installed
to keep fluid in the lines?
