2008 Mercedes clk350...wipers work but when u shut them off they park in the upright position on the windshield...you can push them back down but as soon as you start the car they pop right back up...any ideas??

 

Usually the motor is the problem.

 

But the wiper motors working fine..the intermittent..low and high..its just when you shut them off it stays in the up position..can something be adjusted or repositioned?..it seems like it jumped some gears or something...
