Re: Vacuum wiper system behaving erratically

Assuming the problem isn't mechanical with friction that comes and goes in the cables and/or sheaves, I'd be looking for a stray vacuum leak that can come and go, and then I'd check the vacuum booster pump. Take it apart and of course check the diaphram and it's action, but pay particular attention to the pair of one-way valves.
