Hey guys
again, sigh, i have another problem
after fixing my trunk today (woot!) i felt really great...but then the realization slapped me in the face. I had another problem

I've had this problem for a while, but since you guys helped me with the trunk switch problem, ill ask you guys about this too...

Ok so, I have an 1995 525i and I love it to death:p
But around a year ago the alarm beeper stoped working
I can press the buttons on the fob and hear the alarm lock and arm, but the horn wont sound. and furthermore, when i set off the alarm, all the car does is flash the lights, but doesnt sound the horn anymore.

Why??
but more importantly
cani fix it??:D

Thanks in advance.....

oh and one more question, does the alarm have its own horn, or does it use the same horn as the steering wheel??

The alarm usually has it's own horn, typically mounted under the hood/bonnet somewhere, often on the inner fender. Some have a keyhole on the horn unit to turn the alarm on or off.

on a us 525i would it be on the drivers side or the passengers side

The alpine box has a DIP switch that allows it to use either the car's highway horn or a dedicated horn.

A lot of cars have the dedicated horn because the dealer techs got a few more FRUs to install it and it wasn't much work.

The horn can be mounted on either side, and could look something like this:

In that case, the alarm might be run through the steering wheel horn, or it might be well hidden. I've seen one that was mounted below the ventilation openings beneath the windshield amidst wiper linkage. Look for a horn-like thing.

Those toot when you press the center of the steering wheel. They're ordinary car horns. However, some alarm systems do toot one or both of those horns.

Those are normal horns. Your alarm horn is under the panel (back of the firewall) where the blower motor is located. Check under your rear seat, you may have a wire problem, diconnected plug or a bad fuse. Even the horn could be bad at about $100 or so . BTW, somew cars have sirens installed instead of a horn.

Firewall is the partition between the interior and the engine bay. Remember I mentioned the alarm horn might be under the vents below the windshield, amid the wiper mechanism and such? That's the back of the firewall.

Your arrows are pointing at a plastic cover over some wiring, but behind that is the firewall.
