Wipers

[Smitty]

What level of performance can I ultimately expect out of my original vacuum wiper? It has been rebuilt but is sketchy at best. Dont care for the Rainx solution and would be happy to switch to electric wiper except it would limit how far I am able to open the windshield. I keep the windshield full open during the summer months closing it only in the rain. Daily driver, she is in the rain all the time. Sometimes even in the snow;-)
