Relay and fuse block

The relay and fuse block is serviced as a unit with the instrument panel wire harness. If any internal circuit of the relay and fuse block or the relay and fuse block housing is faulty or damaged, the entire instrument panel wire harness unit must be replaced.

WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, DISABLE THE AIRBAG SYSTEM BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.
