I have a 2001 Elantra which is having central locking issues. The remote works fine and locks/unlocks without issue. However when you press the unlock key the doors lock themselves again almost instantly. It also unlocks/locks itself randomly when driving, when the remote isn't in use.
I have changed the remote battery but this has not made any difference.
Has this happened to anyone before? I was suspecting water in a connector or frayed wire but cannot find anything.
