Flashers

Print

REPLACEMENT



Early models (97) have separate flashers for the turn signals and hazard flashers. They are located on the junction (fuse) block under the cover on the left side of the instrument panel. The hazard warning flasher is the upper one; the turn signal flasher is the lower one.

The flasher contains sophisticated internal circuitry that cannot be tested with conventional equipment.

Models from 98 on use a combination flasher. This flasher is mounted either on the front or on the back of the junction block.

The combination flasher is a smart relay that functions as both the turn signal system and the hazard warning system flasher. It is designed to handle factory-fitted equipment. If aftermarket equipment is added to this circuit (such as trailers with lights), the flasher will automatically try to compensate to keep the flashing rate the same.

  1. The flasher contains sophisticated internal circuitry that cannot be tested with conventional equipment. Substituting a new unit for a suspected defective version is the easiest test.
  2.  
  3. On air bag-e quipped vehicles, disconnect the battery negative cable(s) and wait two minutes from the air bag capacitor to discharge.
  4.  
  5. Remove the junction block cover. If the flasher is accessible, grasp and pull the flasher from the fuse panel.
  6.  
  7. If the flasher is not mounted on the outside of the junction block, remove the steering column cover from the instrument panel. Reach through the opening to access the fuse block on the back of junction block. Pull off the flasher.
  8.  
  9. Inspect the socket for corrosion or any other signs of a bad contact.

To install:

  1. Install a new flasher in the connector.
  2.  
  3. Install the fuse panel cover.
