nect and isolate the battery negative cable, remove
the test radio receiver, and go to Step 5.
(5) Disconnect the wire harness connector at the
inoperative speaker. Check for continuity between
the speaker feed (+) circuit cavities of the radio
receiver wire harness connector and the speaker wire
harness connector. Repeat the check between the
speaker return (–) circuit cavities of the radio
receiver wire harness connector and the speaker wire
harness connector. In each case, there should be con-
tinuity. If OK, replace the faulty speaker. If not OK,
repair the open speaker feed (+) and/or return (–) cir-
cuit(s) as required.
(6) For each inoperative speaker location, check for
continuity between the speaker feed (+) circuit cavi-
ties of the radio receiver wire harness connectors and
the power amplifier wire harness connectors. Repeat
the check for each inoperative speaker location
between the speaker return (–) circuit cavities of the
radio receiver wire harness connectors and the power
amplifier wire harness connectors. In each case,
there should be continuity. If OK, go to Step 7. If not
OK, repair the open speaker feed (+) and/or return
(–) circuit(s) as required.
(7) Check for continuity between the two ground
circuit cavities of the power amplifier wire harness
connector and a good ground. There should be conti-
nuity. If OK, go to Step 8. If not OK, repair the open
ground circuit(s) to ground as required.
(8) Check the power amplifier fuse in the junction
block. If OK, go to Step 9. If not OK, repair the
shorted circuit or component as required and replace
the faulty fuse.
(9) Install the radio receiver. Connect the battery
negative cable. Check for battery voltage at the
power amplifier fuse in the junction block. If OK, go
to Step 10. If not OK, repair the open fused B(+) cir-
cuit to the PDC as required.
(10) Check for battery voltage at the two fused
B(+) circuit cavities of the power amplifier wire har-
ness connector. If OK, go to Step 11. If not OK, repair
the open fused B(+) circuit(s) to the fuse in the junc-
tion block as required.
(11) Turn the ignition switch to the On position.
Turn the radio receiver on. Check for battery voltage
at the radio 12 volt output circuit cavity of the power
amplifier wire harness connector. If OK, go to Step
12. If not OK, repair the open radio 12 volt output
circuit to the radio receiver as required.
(12) Turn the radio receiver off. Turn the ignition
switch to the Off position. Disconnect and isolate the
battery negative cable. For each inoperative speaker
location, check both the amplified feed (+) circuit and
the amplified return (–) circuit cavities of the power
amplifier wire harness connectors for continuity to
ground. In each case there should be no continuity. If
OK, go to Step 13. If not OK, repair the shorted
amplified feed (+) and/or amplified return (–) cir-
cuit(s) to the speaker as required.
(13) For each inoperative speaker location, check
the resistance between the amplified feed (+) circuit
and the amplified return (–) circuit cavities of the
power amplifier wire harness connectors. The meter
should read between 2 and 28 ohms (speaker resis-
tance). If OK, replace the faulty power amplifier. If
not OK, go to Step 14.
(14) Disconnect the speaker wire harness connec-
tor at the inoperative speaker. Check for continuity
between the amplified feed (+) circuit cavities of the
speaker wire harness connector and the power ampli-
fier
wire harness connector. Repeat the check
between the amplified return (–) circuit cavities of
the speaker wire harness connector and the power
amplifier wire harness connector. In each case there
should be continuity. If OK, replace the faulty
speaker. If not OK, repair the open amplified feed (+)
and/or amplified return (–) circuit(s) as required.

REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Remove the trim panel from the front door.
(Refer to 23 - BODY/DOOR - FRONT/TRIM PANEL -
REMOVAL)
(3) Remove the screws that secure the front door
upper speaker to the back of the trim panel.
(4) Remove the front door upper speaker from the
trim panel.
INSTALLATION
(1) Position the front door upper speaker to the
back of the trim panel.
(2) Install and tighten the screws that secure the
front door upper speaker to the trim panel. Tighten
the screws to 1.3 N·m (12 in. lbs.).
(3) Reconnect the door wire harness connector to
the front door upper speaker wire harness connector.
(4) Install the trim panel onto the front door.
(Refer to 23 - BODY/DOOR - FRONT/TRIM PANEL -
INSTALLATION).
(5) Connect the battery negative cable.
