The latest issue to arise is the wipers. The other day the wipers stopped working on the intermittent setting while driving. There was a grinding noise like the mechanism wanted to move but the wipers would not move. I changed the setting to low & high while continuing to drive but nothing happened. They stayed stuck. When I shut off the car & restarted it they began working again. It has happened again since and seems to be only when they are set on the intermittent or delay mode. Any thoughts on where to focus? Thanks
