The fuse block on all models is located under the left hand side of the instrument panel. All flashers are mounted on the fuse block. Each fuse is marked on the fuse block as to which circuit it is protecting. Some early models also use an in-line 30 amp, fuse for the air conditioning hi-blower, located at the cowl relay and an in-line 10 amp fuse for power antennas.

To determine whether a fuse is blown, remove the suspect fuse and check to see if the element is broken. If so replace the fuse with one of equal amperage value.
