For the last 6 or so months ive had this little problem where all the indicators will just come on and permanently stay on, sometimes it would turn off on its own or i had to disconnect the battery to stop it, sometimes it might have occurred twice a week or sometimes not for months.

Now i took it to ford for them to have a look and they said it was probably the relay, so we fitted a new one and it seemed ok(must have been a coincidence) because 2 weeks later(few days now) the indicators came on agian, so i took out the relay myself and the indicators didn't go off? what does that tell me?
Today whilst washing the car i noticed there seemed to be abit of water in the passenger side side repeater, maybe water is getting in and shorting it?

what do you think is causing this?

I dont have an aftermarket alarm fitted, just the standard fit ford gear
