When I get in and close the door the overhead light goes out, then as I start to drive the doors lock. This is normal. The problem is that as I drive along the overhead light will come on and the doors will unlock. If I then push the overhead light switch the light will go out and the doors will again lock.
When I turn the key off the doors unlock automatically as normal.
On a long drive this unlocking can happen several times (perhaps every
15 minutes). It seems to happen completely randomly.Any ideas as to the cause or how to fix this?
Thanks, EJ in NJ
