It's 2006 but think it's preface lift, alarm keeps going off and stopping ,iv pulled fuse for the moment to stop it beeping, I also have no central locking remote doesn't work, wipers and windows wont work , iv heard something about gm5 module might be the issue, Can someone tell me if all these issues are all related or do I have individual problems, thanks for your help in advance
