Windshield wiper not variating during rain fall rate
The windshield wiper does not glide according to the rain fall rate. When I move the handle(to the right ) on the steering wheel up each notch, the wiper glides only once and goes back to its default stationary position on the cowl. (The small incrementing turns on the tip of the handle does not work also) . It does not glide at all if the handle is in 1st and 2nd lift position of the the 3 positions available(the 3rd position is the highest which the wiper glides the fastest and non-stop) which which would be a big help in variable rain rate situations, as it gets tiring to manually move the wiper handle while having to drive.
My local shop guessed roughly by saying it might be costly, as it may entail replacing the rain sensing until and taking the windshield out. Any specific ideas on cost and is normally done to fix this?
