I would like to know where is the horn relay & alarm horn to replace & fix on my audi tt
Tighten the screw on the back or side of the horn. That increases the sound.
If You Just Press The Button Once It (horn) Does Not Sound.. Try Pressing Button Twice.... To Test Your Car Alarm Roll Down Your Driver Side Window,Get Out And Set The Alarm; Then Reach In And Open Door, Alarm Should Sound... If Not Have It Serviced........ Hope This Helps....
pull fuse 4 horn for temp. fix
car horn, siren, gun shot alarm thunder
The first thing is to see if there is a spare N.O. set of contacts on the alarm relay. If there is a spare set of contacts connect your horn supply to one side of the N.O. contact terminals. Connect the horn to the other side of the N.O. contact terminals. Energize the horn circuit's supply. Now when the alarm circuit relay activates the horn will sound.
It depends why it isn't working. You need to find where the power stops between the horn button to the horn. If power gets to the horn and it doesn't sound, it will probably need a horn.
If you deactivate the horn your car will not pass the state inspection next time. In order to get rid of the problem you have to reprogram the alarm system. For that you have to find out which alarm system you have. If you have an aftermarket alarm system then you can check the alarm system manufacture website for instructions. If the alarm system was installed by the manufacture you have to contact a local car dealer (the same manufacture of course).
Replace it.
The horn wire going to the steering column is undoughtly shorting out. Have it looked at as the steering wheel has to come off etc.
