No. Check the metal valve and the white plastic filter.

Classic wiper door solenoid issue. Clean or replace it. It is located on the back of the tach.
Here is how to disassemble and clean.

Did you test the new wiper arm vacuum relay switch before you installed it? All the new cheaper ones test bad. Only the one from Lectric Limited, (sold also by Willcox and now Ecklers) is good. Costs about $60.00 compared to $25.00.

I have ordered two of these from two different places and both were impossible to suck any vacuum through...very little, like it was blocked.....put the original one back on.
