Hello All.  Hope this gets out.A couple of years back, as I was travelling the PCH, I stopped into Van Cafe and purchased a relay that allowed me to change my interval wiper speed.  That is accomplished by quickly pulling up on the windshield squirter.  I loved it and used it often.  So often, in fact, that now my squirter, and with it the interval changer, are not working properly.  Those arms have been an area i would rather not mess with, but here goes.  Any e-mail diagnostics?  Have others experienced this and what is one to do?
