Fuse Block and Fuses

Print

See Figure 1

The fuse block on most models covered by this information guide is located under the instrument panel to the left of the steering column. The fuse block should be visible from underneath the steering column, near the pedal bracket. If the panel is not visible, check for a removable compartment door or trim panel which may be used on later models to hide the block.

Each fuse block uses miniature fuses (normally plug-in blade terminal-type for these vehicles) which are designed for increased circuit protection and greater reliability. The compact plug-in or blade terminal design allows for fingertip removal and replacement.

Although most fuses are interchangeable in size, the amperage values are not. Should you install a fuse with too high a value, damaging current could be allowed to destroy the component you were attempting to protect by using a fuse in the first place. The plug-in type fuses have a bold number molded on them and are color coded for easy identification. Be sure to only replace a fuse with the proper amperage rated substitute.

A blown fuse can easily be checked by visual inspection or by continuity checking.

REPLACEMENT



  1. Locate the fuse for the circuit in question.
  2.  

When replacing the fuse, DO NOT use one with a higher amperage rating.

  1. Check the fuse by pulling it from the fuse block and observing the element. If it is broken, install a replacement fuse the same amperage rating. If the fuse blows again, check the circuit for a short to ground or faulty device in the circuit protected by the fuse.
  2.  
  3. Continuity can also be checked with the fuse installed in the fuse block with the use of a test light connected across the 2 test points on the end of the fuse. If the test light lights, replace the fuse. Check the circuit for a short to ground or faulty device in the circuit protected by the fuse.
