8E - 10 INSTRUMENT PANEL SYSTEMS
DIAGNOSIS AND TESTING (Continued)
(2) The relay normally closed terminal (87A) is
connected to terminal 30 in the de-energized position,
but is not used for this application. Go to Step 3.
(3) The relay normally open terminal (87) is con-
nected to the common feed terminal (30) in the ener-
gized position. This terminal supplies battery voltage
to the cigar lighter or power outlet when the relay is
energized by the ignition switch. There should be
continuity between the accessory relay wire harness
connector cavity for relay terminal 87 and the acces-
sory relay output circuit cavity in the cigar lighter or
power outlet wire harness connector at all times. If
OK, go to Step 4. If not OK, repair the open acces-
sory relay output circuit to the cigar lighter or power
outlet wire harness connector as required.
(4) The coil battery terminal (86) is connected to
the electromagnet in the relay. The accessory relay
wire harness connector cavity for this terminal
should have continuity to ground at all times. If OK,
go to Step 5. If not OK, repair the open ground cir-
cuit to ground as required.
(5) The coil ground terminal (85) is connected to
the electromagnet in the relay. It receives battery
feed to energize the accessory relay when the ignition
switch is in the Accessory or On positions. Turn the
ignition switch to the On position. Check for battery
voltage at the fused ignition switch output (acc/run)
circuit cavity of the accessory relay wire harness con-
nector. If not OK, repair the open fused ignition
switch output (acc/run) circuit to the ignition switch
as required.

(1) Remove the protective cap or the cigar lighter
knob and element from the cigar lighter/power outlet
receptacle shell. Check for continuity between the
inside circumference of the cigar lighter/power outlet
receptacle shell and a good ground. there should be
continuity. If OK, go to Step 2. If not OK, go to Step
3.

(2) Turn the ignition switch to the On position.
Check for battery voltage at the insulated contact
located at the back of the cigar lighter/power outlet
receptacle shell. If OK, replace the faulty cigar
lighter knob and element. If not OK, go to Step 3.
(3) Turn the ignition switch to the Off position.
Disconnect and isolate the battery negative cable.
Remove the instrument panel accessory switch bezel.
Check for continuity between the ground circuit cav-
ity of the cigar lighter/power outlet wire harness con-
nector and a
continuity. If OK, go to Step 4. If not OK, repair the
open ground circuit to ground as required.
(4) Connect the battery negative cable. Turn the
ignition switch to the Accessory or On positions.
Check for battery voltage at the accessory relay out-
put circuit cavity of the cigar lighter/power outlet
wire harness connector. If OK, replace the faulty
accessory switch bezel unit. If not OK, refer to
Accessory Relay in the Diagnosis and Testing sec-
tion of this group for further diagnosis.

REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) If the vehicle is so equipped, move the tilt
OR
steering column to the fully raised position.
(3) Remove the knob and shaft from the headlamp
switch. Refer to Headlamp Switch in the Removal
and Installation section of this group for the proce-
dures.
(4) Remove the two screws that secure the steering
column opening cover to the instrument panel (Fig.
3).
(5) Pull the upper edge of the steering column
opening cover straight back and down away from the
instrument panel as far as possible.
(6) Rock the lower edge of the steering column
opening cover rearward to disengage the hinge hook
formations on the lower edge of the cover from the
hinge pins on the lower edge of the instrument panel.
