Horn Switch; Horn - Chrysler neon 1997 Service Manual

8G - 2 HORNS
DIAGNOSIS AND TESTING

HORN

(1) Disconnect wire connector at horn.
(2) Using a voltmeter, connect one lead to ground
terminal and the other lead to the positive wire ter-
minal (Fig. 3).
(3) Depress the horn switch, battery voltage
should be present.
(4) If no voltage, refer to Horn System Test. If volt-
age is OK, go to Step 5.
(5) Using ohmmeter, test ground wire for continu-
ity to ground.
(6) If no ground repair as necessary.
(7) If wires test OK and horn does not sound,
replace horn.

HORN RELAY
(1) Remove horn relay.
(2) Using ohmmeter, test for continuity between
ground and circuit 65 of horn relay.
(a) When the horn switch is not depressed, no
continuity should be present.
(b) Continuity to ground when horn switch is
depressed.
(c) If continuity is not correct repair horn switch
or wiring as necessary, refer to Group 8W, Wiring
Diagrams.
(3) Insert a jumper wire between circuit 63 and 66
of the Power Distribution Center.
(a) If horn sounds replace relay.
(b) If the horn does not sound, install horn relay
and refer to Horn Test.
(4) Using voltmeter, test voltage at:
(a) Circuit 62 and 66 test for battery voltage
from fuse C to body ground.
(b) If voltage is incorrect repair as necessary.
Refer to Group 8W, Wiring Diagrams.

(5) Check relay for 70 to 75 ohms resistance from
terminal 85 to 86 (Fig. 4). If resistance not OK,
replace relay.

HORN SWITCH

(1) Remove horn relay from the Power Distribution
Center.
(2) Using ohmmeter, connect one lead to ground
and the other lead to cavity 65 of the power distribu-
tion center (Fig. 5).
(3) Depress horn switch, should have continuity. If
no continuity go to Step 4.
(4) Test continuity at horn switch, remove the
Driver Airbag Module. Refer to Driver Airbag Module
Removal and Installation procedures.
(5) Using ohmmeter, connect one lead to the air-
bag module ground and the other lead to B+ wire
(Fig. 6).
(6) Depress horn switch, and the meter should
show continuity. If no continuity, replace the Driver
Airbag Module. If OK, repair as necessary.
