Chrysler 1997 Stratus Convertible LHD, Service Manual, Page: 307 / 1196

(b) If the horn does not sound, go to Step 4.
(4) Remove driver airbag module from steering
wheel. Refer to Group 8M, Restraint Systems for
proper procedures.
(5) Test continuity across horn switch wire to the
airbag metal housing with horn switch depressed.
(a) If continuity is detected, check for a open
circuit between the relay and the horn switch.
(b) If NO continuity:
(I) Remove the horn attaching screws. Refer to
Horn Switch Removal and Installation proce-
dures.
(II) Lift top of outer cover and check continu-
ity between the horn wire and the horn switch
ground contact. If no continuity replace horn
switch. If OK, check airbag module surface for
corrosion, repair as necessary.
(6) Install horn relay into Junction Block.
(7) Disconnect the wire connectors from horns.
(8) Using a voltmeter, with the horn switch
depressed test voltage across horn connector termi-
nals of the wire harness (Fig. 1).
(a) If voltage is detected, replace horns.
(b) If NO voltage, go to Step 9.
(9) With the horn switch depressed, test for volt-
age between the X2 circuit and ground.
(a) If voltage OK, repair system ground at right
cowl area. Refer to Group 8W, Wiring Diagrams.
(b) If NO voltage, repair open X2 circuit between
the relay and the horns.
SYSTEM TEST
CAUTION: Continuous sounding of horns may
cause horn relay to fail.
Check fuse 8 in the Junction Block, and refer to
Horn System Test.
HORN SYSTEM TEST
CONDITION POSSIBLE CAUSE CORRECTION
Horn sounds continuously.
NOTE: Immediately unplug horn and
relay in the Junction Block (1) Faulty horn relay.
(2) Horn control circuit to relay shorted
to ground.
(3) Pinched horn switch wire under
Driver Airbag Module.
(4) Defective horn switch (1) Refer to horn relay test.
(2) Check horn relay terminal 8 in the
Junction Block for continuity to ground
indicates:
(a) Wiring harness shorted to ground.
(b) Find the short and repair as
necessary.
(3) Remove Driver Airbag Module and
check for rubbing, shorted or loose
wire connector and repair as
necessary.
(4) Replace Driver Airbag Module.
Horn sound intermittently as the
steering wheel is turned. (1) Horn relay control circuit X3 is
shorted to ground inside steering
column or the wheel.
(2) Pinched horn switch wire under
Driver Airbag Module
(3) Defective horn switch (1) Remove Driver Airbag Module
and/or steering wheel as needed.
Check for rubbing or loose wire/
connector, repair as necessary.
(2) Replace Driver Airbag Module.
(3) Replace Driver Airbag Module.
Horn does not sound (1) Check fuse 8 in the Junction
Block.
(2) No Voltage at horn relay terminals
6 & 8, and fuse is OK.
(3) Defective or damaged horn.
(4) Defective horn switch (1) Replace fuse if blown as repair as
necessary.
(2) No voltage, Repair or replace
Junction Block as necessary.
(3) Voltage at horn when horn switch
is pressed, replace horn.
(4) Replace Driver Airbag Module.
Fuse blows when horn is blown (1) Short circuit in horn or horn wiring (1) Remove horn relay, check for
shorted horn or horn wiring.
Disconnect horn wire harness to
isolate short and repair as necessary.
Fuse blows without blowing horn (1) Short circuit (1) Remove relay, install new fuse, if
fuse does not blow replace horn relay.
If fuse blows with relay removed,
check for short to ground with
ohmmeter on circuit between terminals
6 & 8 and the fuse terminal. Repair as
necessary.
NOTE: For wiring repairs refer to
Group 8W, Wire Diagrams.
