GM Cadillac 1967-1989 Repair Guide

Fuses and Flashers


See Figures 1, 2, 3 and 4

The fuse block on the models covered in this guide is located underneath the far left side of the instrument panel, up towards the floor mat. Two types of fuses have been used since 1967: the conventional type (cylindrical) fuse, found on 1967 through 1978 cars, and the new "Mini" fuses, found on 1978 and later models. The conventional fuses are held in the fuse block by small tangs, and are best removed with a small screwdriver or awl. The mini fuses are simply pushed into their respective places in the block.

To determine whether either type of fuse is blown, remove the suspect fuse and examine the element for a break. If the element (the strip of silver metal inside) is broken, replace the fuse with one of equal amperage. Some fuses have their amperage value molded into the fuse end, others (and all of the mini fuses) have a color coding system. See the fuse color chart for common amperage values.

The turn signal flasher is located under the dash to the right of the steering column on most models. The hazard flasher is under the dash, to the left of the steering column. On 1980 and later models, both the turn signal flasher and the hazard flasher are located at the lower left hand and the upper right hand corners of the fuse block respectively. There is an inline fuse for the underhood/spotlamp circuit. The fuse box is marked to indicate fuse size and the circuit(s) protected.
