Started with the drivers side lock not working and has progressed to all 4 locks not working with keyless entry and electric switch inside cab. I armed and locked my vehicle and expected the vehicle to be locked when it wasn't and items were stolen from my truck.
All of the indicators in the instrument cluster sometimes read '0' upon initial startup. Sometimes by turning the ignition off, withdrawing the key, and open/close the door then restarting the vehicle the problem corrects itself. However this procedure may be repeated up to 15 times before problem is corrected or, more often, it isn't corrected.
