Fuse box diagram (fuse layout), location, and assignment of fuses and relays Renault 25 (1983, 1984, 1985, 1986, 1987, 1988, 1989, 1990, 1991, 1992).
Checking and Replacing Fuses
Your vehicle’s electrical system is protected from overloading by fuses. If any electrical component does not work, check the condition of the fuses. If a fuse has blown, the inside element will be melted.
Before changing a fuse, it is necessary to:
- Switch off the ignition and all electrical consumers,
- Identify the failed fuse using the fuse allocation tables and diagrams below,
- Identify and correct the cause of the problem.
When replacing a fuse, you must always:
- Use the special tweezer to extract the fuse from its holder and check the condition of its element,
- Replace a failed fuse by one of the same rating (same colour); the use of a different rating fuse could cause a fault (risk of fire).
If the same fuse blows again, avoid using that system and have the vehicle’s electrical system checked by a Renault dealer or a qualified workshop as soon as possible.
Notice
- Never use a fuse of a higher or lower amperage rating than that specified. Never replace a broken fuse with anything other than a new fuse (such as wire, foil, etc). This could damage the electrical system or cause a fire.
