In this complete how-to video, I show you how to open, clean, and reassemble the prefuse box (F32) on a Mercedes-Benz CLS-Class (W219). The walkthrough is based on a 2005 Mercedes-Benz CLS55 AMG (M113K engine), but the procedure applies to many other models that share the same or similar chassis and electrical layout.
