Alarm horn will not turn off
do you have the alarm option, factory?
there are 2 horns
and 1 horn relay.
if the horn relay is energized, then the inputs to it are bad.
bad input is the horn relay has 12v across is coil pins, all the time.
so unplug the horn wires. silence.
then check relay , now that its quiet. is the coil hot?
hot means 12vdc across it. not thermal hot.
the relay on the 97 can be active for 2 reasons.
1: horn button stuck on, so pull that wire.Gray-org, at column
2: BCM is active same color, C2 in 13 is 0volts. (active)
if the BCM is honking the horn, we ask why, and that be alarm.
im reading at alldata.com so can you , under antithieft alarm sections.
if the alarm is activated, (is it) and any door switch is open, the horn honks.
if the gray-org. wires is at 12vdc , then the relay is bad
shorted, main contacts inside.
if the wire is 0v, its wrong.
ill stop, and wait until you find which it is, bad relay, bad horn button
or bad BCM or bad input to BCM.
