Fuse box diagram (fuse layout), assignment of fuses and relays BMW 3-Series E36 (1990, 1991, 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, 2000) 316i, 316g, 318i, 318is, 318ti, 318tds, 320i, 323i, 323ti, 325i, 325td, 325tds, 328i, M.
Checking and Replacing Fuses
If an electrical device fails, switch it off and check the fuse.
The fuse box (electrical distribution center) with spare fuses, relays, and plastic tweezers, is located on the left-hand side of the engine compartment.
- Press the retaining flap in and lift off the cover;
- Remove the fuse of the defective consumer from the socket with the plastic tweezers;
- If the fuse is burned through (the metal wire will have melted and separated), replace it with a new fuse of the same ampere rating;
A list of the fuses with their respective ampere ratings and the equipment in their circuits is provided in the fuse box lid.
Warning!
- Do not patch burned-out fuses or replace them with fuses of a different color or ampere rating, since this could cause an overload on an electrical wire and lead to a fire in the vehicle.
- If the fuse continues to burn through, refer the problem to a BMW Retailer for repair.
Front power distribution box
It is located on the left side of the engine compartment.
