Alarm on Astra S reg

It's started going off every couple of minutes, the handbook states that if
there's a fault in the alarm system the hazard warning light switch will
flash which it does. The handbook states consult main dealer. I suppose
that's gonna cost a few bob. Any ideas.

Ta.

If it is just the siren going off and not the indicators flashing it will
probably be the power sounder that has failed. New one will need
programming by a dealer and they will need the car security code.

 

Everything's going off, indicators etc.

Ron

 

Have a look at the obvious - bonnet switch - boot switch. If all ok you need
to bite the bullet and go to your local dealer. They will tell you what
caused the last 9 alarm activations and any fault codes in the memory

 

Thanks for that, I have found the sounder by the front O/S wheel and removed
the connection, this seems to have stopped the fault light for the alarm
flashing and the flashing indicator lights are not operating either so it
looks like I've killed the alarm. It will do for now till I can get to a
dealer, at least I can lock the car and leave it. Thanks.

Ron

 

I thought that by removing a wire from a sounder I found that I had killed
the alarm as the fault light on the hazard warning switch no longer flashed
after locking the doors. However it went off again a few times today, is
there a way to pull a fuse or something to dissable the alarm only.

TIA

Ron

 

no,
but, turn on the ignition and remove the edge connector from the sounder
unit.
replace the same way.
make SURE you have the ignition ON (one back from actually starting the car)

else the thing will go off forever more!

Many thanks Mike I'll give it a go if I can find the sounder, there are 2
what appear to be horn type things down by the front O/S wheel but I've
removed the wire from both of these (one at a time) and the alarm still
activates. I'll have to activate the alarm and do a search for the sounder.

Ron

 

The sounder is behind the wheel arch liner on the near side front wheel. It
is at the back part so you only need to pop the clips out for that bit.

 

Many thanks, I've just come back to ask exactly that question, I couldn't
find it to save me life.

Ron

 

just don't forget to have the ignition on.
else its lots of wet towels or a very large field and a cardboard box full
of wet towels.

had one a couple of years ago where the owner insisted the batteries were
gone.
so after mucho arguement we took it out and gave it to him,
in a box.
his wife phomed some 3 hours later to ask how to 'turn it off'

we told her it had to go back inthe car and that if it was faulty it would
have died by now.

back came hubby.
we refitted it.

bye bye, hubby

You've probably moved on from here, but if you open the osr door, reach
inside and push the locking button on the drivers door that shoul lock the
car without turning on the alarm.

Mike

 

Thanks for that Mike, can't get to look at it yet as regards the wire on the
alarm sounder, it's done nothing but rain here for the last 2 days. That'll
do until I can get underneath when the grounds finally dry.

Ron

 

Thank Mike, I've removed the only electrical connection I can find from the
sounder unit, a 3 wire plug, is it sorted now ??

Ron

 

What the ruddyhecks going on here, I actually removed the sounder from the
car altogether (with the ignition switched on) It's been on the drive for 4
hours and the ruddy things just gone off again WITH NO SOUNDER FITTED, this
cars haunted.

Ron

 

what the sounder is still sounding? or the lights a flashing only...which is
what you should now get

ok so that's the major culprit taken out of the circuit,
ok round to the other sugestions that are all valid and create problems

firstly door switches, go around each one and pop or unscrew it from the
frame and have a good look at it
if you have an ohms meter, check it goes o/c - s/c as it should.
look for dirt or grime inside or around the switch.

a good trick i do is to pull the wires off and clip them together with a
croc or bulldog clip, thus keeping the contacts shorted ...i'e door closed .

just as an after thought, if you have one of the "i've left my dog in the
car" buttons to disable the movement sensors (if fitted)
try that.

mike

 

Thanks Mike, a sounder and the lights are going off, I've removed the
sounder under the N/S wheel arch from the car, I'm going to contact the
previous owner and see if there's another alarm fitted.

Otherr than that it looks like a main dealer job.

Ron

 

The mystery deepens. I have found another sounder, it looks like an ordinary
horn to me but it's making the same sound as it's always made when the alarm
has gone off. It was located on the top of the O/S scuttle. I reckon the
proprer sounder has never actually worked since I've had the car as a mate
reckons the proper sounder is very high pitched and a sound like that has
never come from the car. I think somebody has fitted an add on to the alarm
system. I've pulled the wire on the sounder I've found and I'm just waiting
to see if the lights flash when the alarm activates by itself. The previous
owner reckons he never touched it or had a problem. I have set the alarm and
opened the rear door (estate) manually and nothing happened when the light
came on. I would have thought that would set it off.

Ron

 

If it is an estate it has a thing called " Pane Break". There is a small
circuit of wire running around the rear side windows - if the window is
broken the alarm goes off. The drawback is that if either the wire gets
damaged or the little button connector comes off the alarm thinks that the
window is broken and sets the alarm off. You need to check the rear window
wire for damage and look at the connectors..

 

Many thanks Mark.
