2006 jeep liberty. In the middle of the night the jeep would make a honking noise with short honks. We never had the alarm set. What would cause this and how would you turn the alarm system off.

2008, why no post the year.?
fuses checked (tested) fuse 23, 10amp, under hood, !!!!????
did you scan it first to see if there are DTC errors. oh boy lots there are and all very USEFUL.
all else on car work ok, drives ok day or night???????
they want to do mine too. but I wont let them.
i dont park, top down in rain, so, no need,
ok the horn can fail many ways,
id not pick the most hard and most costly first.
ever seen a voltmeter?
on mine its hooked to 3 things, alarm, door locks, and horn button.
so are all 3 dead.????? if yes, id bet it not the button/or clock/spring.
cause an alarm ?
tell the doors, to honk with KEY fob actions. (its programmable)
if that fails. say so.

the horn can fail or its base not grounded.
horns love to fail for base rust. clean it?
hot wire the horn to see if hot honks, cost 0 . (jumper wire)
unplug horn and hot wiring , work?


the horn has no relay on JK its TRANSISTOR driven
from the TIPM. direct drive.
so best is to do an alarm first
why? TIPM gets serial commands off the Can-buss
top HONK
so if the TIPM hears (receives) no command to honk there will be no honking, its on a network now.
so say if you scanned it and had can buss errors to the TIMP
we'd work that first, not horn. SEE

at the dealer they can send a scanner command to the horn
in 1min, work, see it works.

so read the operators guide,
see that page on setting horn options try those.
if all fail , the car must be scanned !

its not wired like 1990 wrangler at all.
i have full docs. so.. ask questions.

it is stuck in anti theft mode you try disconnecting battery and see if it helps. You will have to reprogram as well.

its the door switches they are sticking and telling the car door is open. open and close both doors a few times and make sure they are closed good and try again to make sure it is setting properly you will know cause the care dome light will go and it will emit a short honk when activated!! =) mine just did the same thing

If the radio stays on and goes off as soon as you open the door, this is normal operation. Yes, this one threw me for a loop the first time I saw it also.

As for the lights blinking and horn honking, I would have to do some research to see what normal operation is. Many chrysler products do not have this built into their power lock systems. It depends on the security features of your particular vehicle.

you probably just set off the alarm system

If you have your owner's manual, there is a section that will tell you the exact sequence to press to enable/disable the horn bonk. It has three settings, chirp, honk, and off. The chirp is a really quick chirp of the horn. Honk is a longer honk. Off seems to be what you've set.

I hope this helps.

If this is even possible...which im not sure..you would be best goin to a dealer..and let them show you how to use your alarm remote..the BUMs show do it for nuffin..Good luck

Regulator --common on GM ---sometimes spread to all the windows over time --albeit no warning
---honk honk honk come out window gone attempted break in NO ---the window dropped in the
middle of the night ---Silly ---laugh you bought GM --Ford's No Better

If you look in the jeeps owners manual for the keyless remote section, you can program the horn to honk or not honk when you lock the doors.
