Hi Guys I have been having this strange issue with my front wipers on my 12/2010 2.0TDI mondeo hatch.
Wipers have been stopping anywhere on screen then sometimes start with wiper switch other times have to turn off car to start wipers again.
The other day my son was helping me and he observed that as long as the drivers door and any other door is open the wipers work perfectly. Have checked wiring in door jambs replaced wiper motors and wiper switch.
This door situation is strange any suggestions. Maybe replace ddm.
