most likely the stalk is at fault here, could be the wire from stalk to fusebox for the washer motor has gone though. fyi the stalks changed in 1990, so make sure you get the right ones to match your car. hazard on dash = pre-90, hazard on column = post-90

if you feel handy with the wiring, run a 12v wire to the green/red wire pin on the wiper stalk switch, pin T. a handy place to get 12v is the ignition switch red wire. stuff wire in the back of the socket on both pins. if washers and wiper comes on, you know its the stalks. if not, its the green/red wire somewhere. hope that makes sence!
