1999 Saturn Horn Alarm relay

No Vince

The most likely is that someone tried to break into it and it is the alarm. Horn pads don't self activate. I guess it might be a faulty relay?

USA car not told country and they are not the same some cars have 2 horns, high/low tone if one only is dead that is bingo easy answer.

1999 VW Air-cooled in say Brazil 2003 last.
or the new watercooled beetle, NO VIN told so no easy answers
the history of VW is very complex on the world stage.
no country told , or VIN and by country we mean sold to first. (exports to or made and sold local, like Brazil or mexico)\

the alarm horn runs this logic,
Central control module for comfort system J393
the Dual horns use single relay, sol if both are dead, check the relay.
signal wire 75 powers the relay. and H button connect to the relay pin86 coil, the switch grounds the 86 pin on the relay and it energizes. the relay;.beep, done./
water cooled answer.

On some models you can disable the alarm after you connect the battery by locking and unlocking the driver door with the key.
I would disconnect the horn or pull the relay until you can get the alarm turned off.

horn relay located on the right side kick panel,you will see a row of relays,if horn relay is okay, more likely your horn control pad has a short inside causing horn button contacts to stick causing horn to keep blowing.

Disconnect the fuse for the alarm system or unplug horn relay system to change battery if you unplug fuse you will have to reset the alarm, be sure you know how to do this before disconnecting the fuse to the alarm system. Hope this helps.

If the horn fuse ( Fuse #26 ) is installed and has power on both sides of the fuse, you might want to check that the horn connector is still on the horns.

The horn relay is not serviceable in the fuse panel.

You can test the horn connector for power, the Yellow w/ Light Green wire, when the horn button is pressed.

Find and remove the horn fuse or relay to keep the horn from blasting and attempt to start the vehicle. If it starts inspect the clearance between the horn switch and its ground contact. If there is a factory alarm, which I doubt, that has been reset by disconnecting the battery/battery going dead then call your local Porsche dealer for additional advice.

He more than likely just unplugged the horn relay in the fuse box under the hood. Otherwise check the fuse and if he went through the trouble of actually unplugging the horn from the wire harness, it is located below the driver's side headlight

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.

I put a new started in my 99 camry the alarm went off and I didn't know how to stop it ,now my car doesn't have any power the battery is new but its not giving my car any power.Help...
