89 brougham, can you rebuild or repair the wiper switch?

I have the wipers "always on" problem with a new pump circuit board assembly. Before the new board, there was nothing from the wipers, no movement, no pump action other than a faint click when you pushed the wash button.

If I can't find a dash switch, has anyone ever taken one of these apart and fixed/cleaned it?

Are you sure it's the dash switch? I've replaced the dash switch too many times in Broughams with this issue. The common issue seems to be in the wiper motor relay? But that sounds like the circuit board on the motor. I do know that I've had to replace the motor to to fix the prob, even if the motor itself was good (just a bad relay). When you say pump, are you talking about the washer pump or the wiper motor?
