Renault Master – belongs to a series of light commercial vehicles. In different years, Renault Master was supplied to the markets with different types of bodies, both with a standard and extended base. Modifications of Master with increased load capacity are also known as Messenger and Mascott. This model is a copy of Opel Movano and Nissan Interstar , they have a similar arrangement of blocks. Renault Master 2 generations were produced in 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009 and 2010. During this period, the car was restyled. Renault Master 3 generation was produced in 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018 and to the present. We will provide information on the location of the relay blocks and fuses of Renault Master 3 and 2 generations, show photos of the blocks, a diagram and a description of their purpose. We will highlight the fuse responsible for the cigarette lighter.

Due to the fact that Renault Master was produced for a long period of time with various electrical equipment options and body models, it is impossible to provide one general description of fuses and relays. Be careful, because the manufacturer reserves the right to make changes to the design of the car. Your design of the blocks may differ from this material. If you have any questions, we recommend contacting the official dealer in your region.
In both generations, there are 2 main blocks with fuses and relays. One is in the passenger compartment, on the left side of the dashboard. The second is under the hood, on the left near the pillar.
