Torrential thunderstorm then Alarm goes off repeatedly -Help

[No-Bull]

As title really, first time though the keyfob wouldn't disable the alarm & I had to get in & start it to silence the thing (Loud 'ain't they!!!). Since then it's been sporadic but switchoffable(!). Obviously water disruption as it was possibly the worst downpour I've ever seen, but anyone know which area on the car (3r)is the most likely culprit?
On the upside it's been well & truly leak tested & except for a couple of drops, no problem there:).

You could check the instruction booklet on how to get it to report the fault code. However mine lied in that situation and gave the siren tamper code when in fact it was a corroded sensor under the rear clam. I'd start by checking the latter.

Most likely is the Clam switches. There is one on each clam, and they work by conducting when open. They are open to the elements and hence water in them can set off the alarm.

Get some WD40 and give both a good squirt and a wiggle.

If not then it's into the alarm manual to find out how it tells you what's gone off.

My siren filled with water - Lee told me how to shut it up at 8am on a sunday morning, now that's service!

Hmmm, so where's my front one then?!

[joust]

Err - now you mention it - I'm not sure there is....!

I have had the same thing with mine - but it was water in the plug/socket connector that is just adjacent to the siren. My car definatley does not have switches in the clam shells - I wonder if this was started on later models than mine?

[joust]

I doubt it - my car No 26 had the clam switches on them.

Whilst talking of water, one of my front doors sounds as if its part full of the stuff. Any offers as to how I might 'empty the door'.

Cheers.

1/2 bottle of whiskey and a straw!!

I haven't looked but are there drain plugs in the bottom of the doors??

Removing the door trim panel is easy -

Remove door opener surround (single screw)
Remove interior door handle (single screw)
Remove all screws around outside of door trim.
Remove speaker grill and screws.
Reach in through speaker aperture and along the bottom there are 3 or 4 wingnuts holding the panel on.
Remove door trim

Soak up any water and look for telltale signs of where its coming from - poss rubber wiring bung near hinges or window glass rubber itself

Drill a couple of holes in the underside of the door if you still have a problem and no drainage holes are evident (all cars I have seen have them) I would protect the new holes if you drill them with some resin or similar to protect against possible osmosis

No front clam switch. Vegantune did mention this to Noble as its a security oversight for obvious reasons (to owners) that I won't highlight here.

All now lubed, no recurrence, fingers crossed. Not had time to check fault codes (Too busy wrestling with a wonky set of pipes!).
