I have a Saturn sl2 while driving it the wipers will come on horn will honk or the alarm will go off gauges stop working and the air conditioner will stop, the trunk will pop open security light comes on . I can cut the car off and sometimes it will be working fine and sometimes it want until the horn beeps again or goes through the same sequence. Does anyone know what is going on with my car??

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.

You will need to replace the horn pad or disconnect the horn. Your choice.

hook it up and wait a min or 2 for it to stop or disarm the alarm after but i think it will stop after 1 or 2 mins

it could be the wiper relay or the wiper motor could be heating up and stoping causing it to work again when it cools down either case start with relay and if that does not fix the problem replase the wiper motor

you must remove the steering wheel,air bag and the clock spring and the the whole switch,no easy,way DO NOT DO if you do not know how,you could set the air bag off or mess up the clock spring position and wreck it,,,take it to a shop,if you are not familiar with this kinda repair

You might can have the dealer program it not to honk, but its just the way the keyless entry works. I've owned 2 accords--an 06 and 08--and both of them honk the horn when the lock button is pressed twice. Pressing the button once will secure the car and arm the alarm. So once click is all you really need. And no your alarm is not malfunctioning.

Sounds like your battery has a dead cell. The cranking amps required to start a vehicle is considerably more than to power accessories. The alarm may have a safety feature that will make it go off if the battery voltage is too low (or if someone disconnects your battery). Have your battery tested (with and without a load) and repost if this isn't the problem.

check fuse for horn, if that's ok.

run power wire straight to the horn from battery to test if horn is working,

if that works>> you will have to take cover off steering wheel and check wire hasnt come loose there.


good luck, hope you get it working

its an old car..............................

You need to wire a relay to the horn wire first and then run the wire from the relay to the horn. You need to get a single pole relay. go the auto parts store and tell them what you are doing and they will sell you a basic horn relay. The stock horn had a relay attached to it.
