Window squirters on all the time?

[phishfud]

My wipers/washer system was working fine, but now the squirters are always on. No matter where I set the switch, it just pumps out fluid until there is no more, and even when empty, the wipers are slow since the pump is pumping. Not sure if this is a common problem, but hope to get a good starting point before I throw parts at it. I suspect the wiper switch, but not sure. This is an 84 with cruise and delay wipers on the column. Any info would be great. Thanks.
