I had the dealer diag. electical problem to the heated nozzle on my front right side of car (headlight). All they did was disconnect the unit and the problem with the blown fuses went away (#7 fuse) The part seems cheep, and I would like to DIY.

Is there a serivce number on the cd or could someone explain how to replace this part.
