Fuse box diagram (fuse layout), location and assignment of fuses and relays BMW Z3 (1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002).
Checking and Replacing Fuses
If an electrical accessory should fail, switch it off and check the fuse.
The fuse box (electrical distribution center), which contains 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.
- Use the plastic tweezers to remove the fuse for the accessory or equipment that has stopped working.
- If the fuse is burned through (“blown”), the metal strip will have melted and separated. Replace the blown fuse with a new fuse of the same ampere rating (color code).
A listing of the fuses, their respective ampere ratings, and the equipment in their circuits is provided on the cover of the fuse box.
When you close the fuse box, be sure that the cover is seated securely.
If a fuse burns through again, have the source of the fault checked and corrected by a BMW center.
Warning!
Do not attempt to repair a burned fuse or replace it with a fuse having a different color or ampere rating. To do this could cause a fire in the vehicle resulting from circuit overload.
