As I stated above, they quit working today, and I was hoping someone here could help me out. My car has the rain sensing wipers ( sensor is located in the mount of the rearview mirror) and I was wondering if maybe its just the sensor went bad? the wipers cycle once when I move the stalk to the "intermittent" position, but then thats it, they don't cycle everyonce in awhile, even in heavy rain. They'll also cycle once if I move the switch on top of the steering column stalk ( the one that changes how often the wipers move), so thats why I'm thinking maybe its the sensor, since all the switches still work. anyone have any ideas? how hard is the sensor to change if that is it?
