i got a 1990 Loyale  and my wiper switch is kinda broke, the button for the window sprayer is whats actually broke. everything still works except that. i know the turn signals and wiper switch is one piece, but what im really wondering is can i use a switch with intermittent wiper settings? my car has the basic on and off wiper settings, no intermittent. so im wondering is it a plug and play or is there an extra plug for  that setup mine wouldn't have like a relay or something? thanks for any help.

Howdy 1990loyale. I know it's possible just to put a switch in for the washer fluid control. I've done that before. If I recall, just use the two small wires near the base of the wiper control/arm. White and blue? I actually had to put in a switch also for the wiper itself too since PO have pulled the whole wiper piece out. Oh well. Hey good luck!
