Robert kiely Posted March 17 Share Posted March 17 Hi everyone, im having a problem with my 07 galaxy. I got a message on the dash saying alarm system service required. Since then, the wipers turn on automatically and won’t turn off until I disconnect the battery. I read online that the problem is corrosion in the alarm siren box located in the passenger wheel arch. I took off all the panels but cannot find it. I really don’t care about the alarm, but the wipers are a big issue. Can someone point out where the alarm system might be? If I disconnect that will the wipers work normally again? Is there a fuse for the alarm system I can just take out? I also can’t find that, and there is no mention of an alarm fuse in the manufacturer book. Any help would be greatly appreciated Quote Link to comment Share on other sites More sharing options...
iantt Posted March 17 Share Posted March 17 Recheck the passenger wheel arch. Remove the arch liner and the alarm is up top right corner from what I remember. Been a while since I've replaced those. Will see if I can find an image or such to show you. Quote Link to comment Share on other sites More sharing options...

The fault with the wipers, and very probably the alarm system is more likely to be with the GEM (BCM on later models). It is possible that you have water ingress to the GEM which is a common problem on a lot of models. Quote Link to comment Share on other sites More sharing options...
Robert kiely Posted March 17 Author Share Posted March 17 Have you experienced this problem yourself to be able to say you are certain? I don’t understand how it could be water damaged considering the BCM is in the car under the glove box… 1 Quote Link to comment Share on other sites More sharing options...

Many models of both Ford and others like Vauxhall frequently get water ingress in to the Body Control Modules. How the water gets there is often never known, and sometimes it comes from faulty screen wash pumps like on the Mondeo. Do I think the wipers will work normally if you disconnect the alarm system ? No. The fault might very well not be water ingress to the GEM/BCM on your vehicle but it is worth looking at if you still have a problem with the wipers. 1 Quote Link to comment Share on other sites More sharing options...

Do a search on this forum to see how many people (including myself) end up with a pool of water in the spare wheel well... Quote Link to comment Share on other sites More sharing options...

Hi all, i can confirm that disconnecting the alarm siren does infact make the wipers work like normal again. 1 Quote Link to comment Share on other sites More sharing options...

I'm very much surprised, but as long as it's all working that's the main thing. 👍 Quote Link to comment Share on other sites More sharing options...

Some times companies just don't learn by their mistakes. Focus Mk4 still has it located exactly where the scuttle panel drain is ! 🙁 3 Quote Link to comment Share on other sites More sharing options...
