Default Horn/Lock?

Hey folks, new on here.

I own a 2004 Jetta wagon manual with about 85k miles so far. Great car, I absolutely love it.

Normally when I lock the car remotely with the key/alarm fob thing, the horn makes a little honk to assure me that the car is locked, along with a quick flash of the lights.

Recently, though the horn stopped doing it's thing when I lock the car remotely. Lights still give a nice quick flash, and the car locks as normal, but no little horn beep.

The horn itself does work; I've checked it when the car is running.

I recently installed a bluetooth radio thing for my cell phone that I had to tap into a 12V ignition source from the fuse box. However, the horn lock was working for a few days after I installed this, so it may not be related.

Any ideas?

Thanks!
Geoff

Trunk/hatch/hood, any doors slightly open? or check all fuses. may have blown one.


someone else can tell you if there are any ncluded on OEM stereo in dash that may have been affected, but it depends on the unit installed...monsoon, double din etc i think?

Sometimes mine will lock all but the drivers door and not give me a honk, then if I unlock them again then lock, everything will lock and it will honk, but that might be normal

Yeah, I've been through and checked all the doors/hatch/etc. (It's a wagon.)

I'll have a look at the fuses tonight. Is there some kind of separate remote lock fuse that is separate from the horn fuse? My horn is still working.

The radio is the stock radio; single CD player/tape deck, (seriously Volkswagen? in 2004?) and radio. The unit I installed was a parrot mki9200. great little device for the iPhone, as it turns out.

My Golf does the same thing seemingly at random. It's an '02 with 136k.

Does the panic button work? If not your security horn is dead. Happened to me, I replaced it with a siren. Works better for an alarm then that terrible little horn.

Your driving horn and security horn are two different horns. One is located under the rain tray on the drivers side (security horn) and the other is located just behind your bumper on the drivers side (driving horn).

-Edit-
Another test to isolate the security horn from the rest of the security system. Lock your doors with your fob as you normally would to arm the alarm. Unlock your drivers door using the key, not the remote. Check and see if your 4-ways come on signifying the alarm going off. If the 4-ways go off but no horn 100% your horn is dead or the connection has come loose.

I AGREE! if fuses and latches are all working, this must be it. i bet the ground wire is loose on the security horn.

Get inside your car. Take the keyfob and lock the doors. Open one of the doors. Does your alarm go off?


Occasionally mine doesn't honk, but then it'll just start working again. Personally I find it annoying. I'm content with just the lights flashing.

Thanks for the replies everyone!

A few more fun facts:

The panic button does indeed work.

When I lock myself inside the car with the remote, and then open the door, the little horn does go off and it sounds like it normally does when I lock the car remotely.

When I lock the car remotely and unlock with the key in the driver's side lock, (not the fob), the side flashers do indeed light up quickly.

So the horn works and all the lights flash. Weird, but like I said, mine randomly works, and randomly doesn't. If all is still working except the honk, I wouldn't worry about it.

Funny situation i know. This happens to me too however always fixes itself.

Generally you do want to make sure that all doors are closed, hood etc etc.....Often times my trunk wont latch or lock because it sticks and causes this to happen. I have not had the issue since i greased it however this issue was very prominant when my break switch was faulty. THis caused an open circuit and often times kept my break lights on.

once again though doo check your fuses.

Just disconnect the security system. No one pays attention to alarm systems anymore anyway. If their going to break in or steal your car they will do it with or without the alarm. You cannot stop a determined individual. They will try and try again. Thats why i don't lock my cars.

If they're gonna steal your head unit, its getting stolen. So if the doors are unlocked, at least you don't have to replace your window too

Quite the opposite. My security systems (both the stock VW one and my aftermarkter 2 way security in my old car) have saved me several hundreds of dollars, and possibly thousands of dollars in theft. Not to mention the fun that can be had in scaring the shit out of those damned people who put the flyers under your wiper.
