Well, this is the latest of the symptoms! Started with auto lock feature not working at 15 mph, but clicking noise like trying to lock, then interior lights came on by them selves and doors started unlocking as truck just sat there! This was after using remote lock device, sometimes the lights just turned on and off while truck unlocked an un attended! Next auto door locking feature started working after 15 mph but if you rolled down window, doors would unlock! Latest is doors lock with 15 mph feature but maybe 30 seconds later, the time varies, they automaticlly unlock! Posted this in 2nd Gen but no body replied, am I the only 2002 2500 2WD TD full power, keyless entry that has had this happen? Dealer has started out with what they think but that has changed twice and they have not replaced a single item! Anybody have any thoughts on this? Thanks. TL
