My wipers will operate only on high speed, no mist and will stop at whatever position they are at when turned off. I think the problem is the wiper switch on the steering column but can't find one. Sure there are lots of places that say they can get one. But all of them show pictures of a turn signal/wiper control switch that looks like it goes on the left side of the steering column. Not the wiper control/high beam switch I have on the right side of the steering column. Any advice would be much appreciated.
