Alarm going off !

[nigelw]

Has anybody else had a problem with the alarm going off for no reason . It usually happens if the car is left in heavy rain , but it cant be cancelled by locking or unlocking the doors . I feel that it may be linked to the tailgate switch getting water in it but just wondered if anyone else has had any problems ?

Rear clam alarm switch is know to cause false alarms. Depress it a few times to ensure it operates freely then try cleaning and spraying it.

Check rear clip and door switches... I had this recently when left outside overnight it always happened... It was the door switch!

No, sorry but its an ancient design! For starters, any classic car shop will stock them.

I found a better quality replacement on eBay last year. I don't have a link, but it was called something like heavy duty alarm switch.

If you don't get it sorted from the above suggestions, then lock the car and wait till the alarm sets then pour / splash water onto and around the heater fan motor box under the front clam mainly on the drivers side...

Thanks for this, I typed in as you said and have found a replacement for the crappy old rusty thing and it only cost a couple of quid.

Glad to assist!
