Have a strange problem with the trunk lock on my 14' TG. When not locked, the door stays closed when riding down the road but when locked, it tends to pop open. :xzqxz: This has happened twice now, I was notified by a passing motorist the first time but the second time I didn't know it til I stopped. Anyone have this problem or have any ideas on why this would happen? I've treated the lock with a lubricant and it doesn't seem to be sticking.
